Epic Games claims that Unreal Engine 5 Tech Demo can run with 40fps on RTX2080 notebook at 1440p

DSOGaming writes: "Earlier this week, Epic Games presented an amazing tech demo of Unreal Engine 5 on PS5. That demo was running at 1440p with 30fps and looked spectacular. However, that same demo can already run with 40fps on an NVIDIA RTX2080 notebook at 1440p according to Epic Games China."

[Looper]

Turns out an off the shelf SSD was sufficient to do all of that at a better frame rate on top of that. So much for the flying section using some sort of secret sauce.

Turns out the conclusion those who haven't had a sip at the kool-aid had was correct; just a bunch of paid for marketing baloney.

[Jin_Sakai]

“Turns out the conclusion those who haven't had a sip at the kool-aid had was correct; just a bunch of paid for marketing baloney.“

We’ll see about that kool-aid when Sony 1st party devs start firing on all cylinders with a 5.5Gbps SSD at their disposal.

[ElementX]

Lol level design won't require 5.5Gb per second. There's less then 16GB of RAM available for the GPU on the consoles and they'd both full it up fast enough to do anything. The Series X decompresses at 6GB+/sec. Less than 2 seconds to fill up whatever RAM is used by the GPU, fast enough to fill up the screen with whatever you can throw at it. By the time you moved across the screen the next area would be loaded.

If you actually used 5.5GB+/sec transfer the game speed would be too fast to even be playable. Even the streaming part of the demo was too fast too really do anything other than jump and that wasn't even pushing the SSD to it's limits. The images at the sides of the screen were blurry from the speed, it's just not feasible for gameplay.

[coolbeans]

You're literally not 2 days out from utilizing rhetoric like how that UE5 got MS shook and general gloating about it. You should be the first in line to reconsider your rhetorical approach before pivoting at the nearest convenience.

[Kiwi66]

Mate just admit that you bragged a little too much over the demo reveal and move on

[Hakuoro]

ElementX, what official paper has said 6gb/s?

You guys call out people for talking about PS5 SSD but you guys keep lying about the speed of the SX's SSD to compensate.

And you guys are all over the place yesterday someone was claiming it was over 9gb/s. There is no way that a 2.4GB/s SSD can decompress at 6 GB/s it's simply not realistic. With 2.4 gb/s SSD your looking at 4 to 4.5 GB/s and that's being generous.

If you're going to call people out don't turn around and make up lies in the same sentence.

[Babadook7]

Well, sure, some of Sony's studios will continue to make some of the best looking games around. That's part of why Sony bought those studios and why they encourage them to push the visuals as much as possible. But that doesn't mean that other studios won't make some equally amazing looking games. Quit trying to act like Sony 1st party studios all perform at that level because they don't. Second of all, don't expect sensible people to believe that Sony studios have some secret sauce that just can't be matched by anything else, even PC, because that's just a load of bunk.

It's great what Sony has done with the very fast SSD and supporting architecture, but it isn't the end all be all. GPUs, CPUs and traditional memory bandwidth still matter a lot. A SSD can allow for some really awesome things that will be greatly appreciated this upcoming gen and I'm glad that Sony and Microsoft decided to improve things in that area. But storage speed doesn't overcome every other consideration.

[ElementX]

I'll quote the math from reddit since that's easier than typing everything out on my phone.

"That's why it's 4.8GB/s to 2.4GB/s raw (-50% compression) and the PS5 is \~8/9GB to 5.5GB/s raw (\~-39%/-30% compression). "

Kraken provides about 30 to 40% compression at the time of the spec reveal. Algorithms change and improve. Cerny talked about up to 22Gb, lol.

BCPack compressed at least 50% at the time of the spec reveal. The 6gb decompression is from the Eurogamer article:
" Our second component is a high-speed hardware decompression block that can deliver over 6GB/s," reveals Andrew Goosse". https://www.eurogamer.net/a...

I posted yesterday about a compression expert who believes it to be more than 50% compression. Microsoft hasn't come out with exact numbers yet. So the decompression block can handle over 6gb/sec. Why would they give that number if the compression wasn't capable? Your guess is as good as mine but it leads me to believe that BCPack will get closer to 6gb, thus the compressed IO will be higher than 4.8GB. If they were getting only 4.8GB compressed then they would've said so. It's speculation, of course.

[Babadook7]

ElementX

6 GB/s vs 22 GB/s are the limits.

Sony has about a 3x advantage

Kraken numbers are for the total asset compression so you would have to compare those numbers to the total asset compression on BCPack. Not total vs texture only. Kraken is likely better.

[Hakuoro]

ElementX The spec sheet on that page you linked says 4.8

IO Throughput 2.4GB/s (Raw), 4.8GB/s (Compressed)

Which again, having 2x the speed of the device is highly unlikely. So I don't know where this guy comes up with 6GB/s other than it's Microsoft not being truthful to make a favorable comparison to PS5.

Again I guarantee you that it'll be around 4-4.5 GB/s

[ElementX]

Series X uses BCPack and ZLib from what I've read. BCPack is designed for textures. Textures can be highly compressed, a texture specific algorithm is better than one that does everything. PS5 supposedly also uses ZLib. As algorithms improve, compressed IO improves. I know 22Gb is the limitation, it would never get that good. 6Gb decompression could've been left out of the discussion of it weren't reachable, it may be possible, well have to wait

MS was still improving compression in March

https://twitter.com/JamesSt...

@gaming. Yeah as of the current compression available at the time. That page also talks about the decompression block, which is what I'm talking about. Compression improves all the time

[gravedigger]

@ElementX

BCPack is already included in XSX SSD compression speed 4.8 GB/s, same as Kraken in 9GB/s. But Kraken is a lossless compression, BCPack is lossy compression. Accept, Xbone fans, that XSX SSD is inferior to PS5 SSD

[CH33S3]

God damn it! I wanted to see how this played on PC. I've already dropped some cash on a nice PCIe 4 Corsair drive that comes in at just under 5GBs. I just want to see how it runs with UE5 and what do I get? BS from China that's already been proven to be fake.

Look, I'm not being down on PlayStation. I just game and create on PC mostly and wanted to see requirements. Well. That and whether they'd fixed problems with blueprints (talk about a pain in the ass).

Can we just get some real information from epic already. All this fake shit from fans because PS5 was the reveal platform is crazy.

[umair_s51]

That what I was thinking. Game will probably be already GPU or CPU bound before requiring those SSD speeds.

[ElementX]

@gravedigger it was 50% compression AT SPEC REVEAL. I said 4.8GB(compressed) was 50%! They continuously work on algorithms to improve compression. The compression Sony is using might improve also! We don't know any details about BCPack, the Twitter link I shared was from a MS employee working on compression tech for MS and Series X. He stated that MS has shared further information with developers and partners, however it's not publicly available yet.

I said we have to wait and see if they improve the compression, it may result in 5+GB compressed down to the 2.4GB(raw) IO speed of the SSD. Nothing you stated in your post is anything I haven't said already! Did you even read my previous comments?

[gravedigger]

@Element

Yes, i've read your comments. But somehow with some theorry and quotes you trying to mitigate XSX SSD lower speed compared to PS5s SSD.
Spec is 4.8GB/s compressed ( BCPack within. Theoretical max is 6. YOU CAN'T CHANGE THE LOCKED numbers. That's it. XSX SSD compressed speed is below PS5 RAW. Accept that and move on. BCpack is texture ONLY and lossy one, Kraken is for general decompression and lossless. That means EVERYTHING.

[itsmebryan]

@jil
That's just said. Just take the "L" and move on. Smh

[rainslacker]

All this discussion about compression when all that really matters is physical throughput. Compression just makes the files smaller, it doesnt speed up the actual transfer of bits. Compression, regardless of the technique is never going to achieve a 50% reduction of data across the board. Some things may compress more, others less. Media data doesnt tend to compress well beyond what formats already offer compression for saving.

If a drives actual specs are faster on one system, then it's going to be faster with or without compression. Better compression will only mean that you may be able to transfer more data, but it's highly unlikely two high performance compression algorithms are going to have a significant difference in their compression levels.

[gravedigger]

One interesting tidbit :

"
I think that’s simply a case of crossed wires over running a mp4 of the demo vs talking about how the tech runs on a laptop. In the technical detail, nothing Sweeney or this Q+A reportedly revealed contradict each other. What that Q+A just more explicitly confirms is that Nanite can dynamically scale triangle fidelity according to your data access. 1080p/2tris per pixel should indeed be in the realm of MB/s rather than GB/s. Sweeney already said this will scale down, it just won’t look as good. In saying ‘this needs MB/s, not GB/s’, I don’t think this engineer is at all claiming you’ll get the same fidelity on MB/s. Simply that the tech can scale it down to that level."

https://www.resetera.com/th...

So, MEGABYTES

[Drew345]

@ ElementX

The Series X can compress 4.8GBs of data, not 6GBs.

The demo being ran during the flying scene was not pushing the PS5's SSD to the limit. You say 5.5GBs of UNCOMPRESSED data isn't needed because it would be blurred out. You forget, nothing was going on during that scene, though. The more you have in a frame, the harder it will be to process that information without running into a bottleneck. What does that mean exactly? The PS5's SSD is going to allow a lot more on screen per frame, whether you are falling or just walking around -- especially when that data hits 9GBs compressed.

[UltraNova]

One thing's for sure, if an engine demo got so many people riled up, imagine what a Sony 1st party game will do to them. Fun times ahead!

[Profchaos]

It's been now proven the China leak was completely fake with Tim Sweeney stating they just played the video as is on a laptop the same way people watched it on their device at home.

[Obscure_Observer]

A RTX2080?

According to PCGamer, Xbox Series X´s 12.155 TFLOPs GPU is theoretically faster than a GeForce RTX 2080 Super´s 11.15 TFLOPs GPU

Interesting fact is that PS5´s 10.28 TFLOPs GPU is also theoretically supposed to be a tiny bit faster than Nvidia´s RTX 2080 10.07 TFLOPs.

https://www.pcgamer.com/on-...

Xbox Series X faster GPU and CPU could (on paper) run that demo at superior resolution and framerate in direct comparisson with that RTX2080 notebook.

[MasterCornholio]

What about asset streaming?

[Asuka]

This is incorrect. You cannot compare Turing architecture to RDNA2 in that way.

Turing Tflop != RDNA2 Tflop. This is why I hate the whole Tflop metric. It mean next to nothing unless you are comparing generations of the same gpu architecture.

[Obscure_Observer]

@Asuka

"This is incorrect. You cannot compare Turing architecture to RDNA2 in that way."

Except it´s not me, dude.

https://www.pcgamer.com/on-...

Hit the global authority on PC games at Twitter and speak your mind. :)

[FlyingFoxy]

This was a laptop, a laptop GPU. Laptop GPUs aren't as fast as a desktop GPU.

https://www.youtube.com/wat... This demo would probably run 60fps on a 3070 class card

[Eonjay]

Unfortunately the demo on the 2080 tweet was a fake so we can't say either or. What we do know is that Tim stated that the engine itself can run on both current and next gen.

[anubusgold]

@MasterCornholio The asset streaming doesnt matter since intel is stuck on pcie 3.0 that is why epic was so impressed they are stuck on crap hardware. Intel has the whole market and Amd only had 5 percent of the market so amd hardware is on pcie 4.0 for a year now with much faster ssd speeds up to 4.9 speeds where intel is stuck on 1.5 speed drives. Its so bad at intel that intel have to test their New SSD 4.0 drives on Amd motherboards that has to burn their ass lol. Intel is waiting for Pcie 5.0 then their speeds will be beyond playstation 5.

[amazinglover]

Flops don't translate 1 to1 across architecture so comparing them that way is pointless.
RDNA 2 flops are less powerful then RDNA 3 an RDNA 2 card with 10 TF will be less powerful then an RDNA 3 card with 10TF

until more devs get there hands on both consoles all where doing is making uneducated guess as these run on architecture we haven't heavily tested yet.

[rainslacker]

A flop is a flop. Doesnt matter the architecture. I think what's confusing with the way people are talking about is this perception that a flop can perform a specific amount of work per flop. What is really happening is that different classes of hardware, or core functions can process the data from these flops in different ways, and achieve results using a different amount of data. A streamlined rendering process can theoretically do more with the same amount of data, or the less efficient one may require additional workload to achieve the same results.

In this way, comparing flops from one processor architecture to another is not really prudent. But it's fine when comparing processors from the same class of processor.

There is also the matter of the API that is being used to process the graphics. DirectX and Vulcan for instance handle their render streams in much different ways. One isnt better than the other, at least not for the purpose of this discussion, they're just different, and how well they work on various architectures varies as well.

[anubusgold]

@brrdat Linus tech tips just called out Tim sweeny for lying for Sony he showed 3 ssd's that are at least as twice as fast as the PS5 SSD He clearly shows it at the 22:00 min mark on youtube https://www.youtube.com/wat...

[ABizzel1]

@Obscure_Observer

No Asuka is correct, that article is about TFLOPS only, not performance.

PCGamer should be ashamed of themselves for even posting that article. This article is a comparison of TFLOPS, which has nothing to do with performance when comparing different architectures. NVIDIA cards have almost always had lower TFLOPS than AMD cards, and still perform on par and for the last 10 years beat AMD in the same tiers.

TFLOPS is nothing but the CU * 64 * 2 * the GPU clock speed, which is why it's standard across the board. However, it does not take into consideration the IPC of each CU, or if the CU is combined with other cores (such as RT Cores etc...)

Two different GPU can have 40 and 56 CUs at 2 GHz, using TFLOPS alone the 56 CU GPU comes in at 14.336 TF while the 40 CU GPU comes in at 10.24 TF, and instantly all the non-tech people on this sight would say the 56 CU GPU is better. When in fact if the 40CU GPU has a 50% IPC performance increase then it's still 10.24 in overall TFLOPS, but in reality, it performs closer to 15.36 TFLOPS and is more powerful than the 56 CU GPU even though the TFLOPS are lower.

This is basically the battle NVIDIA was winning against AMD prior to RDNA (closer, but still a bit behind on IPC) and RDNA 2 (hopefully equal).

A prime example, they have the Vega 64 listed 2nd in the ranking because it has high TFLOPS because it has 64CUs, however, it's second to last in game performance only beating the original base RTX 2060, and competes with the RTX 2060s only in games that favor AMD.
https://www.youtube.com/wat...

Please stop spreading misinformation.

The Series X performance ranges around the RTX 2080 and RTX 2080 Super, the PS5's performance ranges around an RTX 2070 super. Therefore, the Series X performance will be on par with this laptop, as the consoles are basically high-end gaming laptops.

[alb1899]

They ran the famous demo on a portable PC with RTX 2080 mobile that has a 9.4 terraflops of performance when is connected but they ran that demo with the portable disconnected and still the PC managed to run 30% faster than the ps5. It takes us AGAIN to the question of how many terraflops does really has the ps5?
I will help....It isn't 10.2.

[Profchaos]

That's not how tflops work rDNA vs turning can't be compared in that way

[Sophisticated_Chap]

alb1899 has a point, since the PS5's GPU has dynamic frequency scaling, so it may not be running at the full 10.3 Tflops the entire time, possibly due to heat. But then again, this could be how RDNA2 Tflops compare to Nvidia Tflops, in which case RDNA2 isn't much better than RDNA1.

Having said that, AMD did say that RDNA2 PC GPUs would be different from what is going to be in the consoles. Perhaps this is the same kind of marketing AMD does with their mobile Ryzen CPUs, where they are calling them Ryzen 4000, but in reality, they're actually Ryzen 3000 (Zen 2) CPUs.

Either way, it's going to be interesting to see the final performance numbers when the time comes.

[Eonjay]

You do realize that this story is a fraud per Tim himself, right?

[itsmebryan]

@brrdat

Where did EPIC say that XSX would not be capable of the demos level of performance? You and other Sony fans are so desperate for a win, you crow about a next generation tech demo running 1440p @30fps. Now who is really desperate? Smh

[Donnie81]

Yeah the 10.28 is just a best case number that will never be reached. They know good and well the ps5 is a 9 tflop machine. Just 10.28 sounds better than 9.28 vs 12 plus.

[Asuka]

I know they are not devs, but Digital Foundry did say in their analysis that the demo appeared to be very GPU dependent. If that is the case then it would make sense that the demo would run better on a rtx 2080 (a downclocked rtx2080 at that since it specifically stated notebook.)

[alb1899]

The performance of a PC portable unplugged is a lot less than plugged. The demo was running at 40fps unplugged

[sinspirit]

@alb1899

This video was debunked as taken out of context and not an actual demo running. They are discussing other information and watching a video on the laptop, hence the ".MP4" on screen.

On top of this faked info. Where would you even get the unplugged info from? Where did you conjure this up from?

They mentioned 40fps as a target to hit to maintain at least 30fps for an acceptable framerate on PC hardware. 30fps with VSync. Tim Sweeney's Twitter states this. This is likely how they will decide levels of fidelity while using these features on existing hardware. They aren't just gonna run the same graphics settings on every type of hardware. Now they gotta experiment with settings to find the sweet spot for different tiers of current hardware.

[GTgamer]

FALSEEEEEEEEE
https://mobile.twitter.com/...
TIM SWEENY says that's a video playing on the laptop you can clearly see mp4. Smfh
Damn UE5 demo really got y'all going crazy nice try tho.
Can't wait to see what else you guys come up with

[Asuka]

Eh I'm still skeptical. who transcodes and plays back a video at 40fps?? Doesn't make much sense, then again most things these days don't...

[GTgamer]

@Asuka
"Not sure exactly what was said. The translated quote on 40 fps isn't a comparison between hardware capabilities. To hit a 100% solid 30 fps with vsync in the demo, per-frame times vary from 30 fps up to much higher."

[Imalwaysright]

Nope Epic's engineer point blank stated that his PC with a mobile RTX 2080 could run the demo at 40 fps but didn't specify the resolution. All Sweeney is talking about is a video from a presentation wich has nothing to do with the claims made by the engineer.

[GTgamer]

@imalwayright proof?
https://www.reddit.com/r/PS...
Here's all my info from the stream translated.
And even if Epic themselves said since day one of the stream UE5 can be downscaled to run on most hardware so what's the point especially since you don't know if it was on the level of the PS5 demo.

[Imalwaysright]

https://pbs.twimg.com/media...

So where did the 40FPS come from? I thought the Epic guy said he was getting that on a laptop, I don't believe they actually claimed it was running on stage on the laptop.

[GTgamer]

@ElementX
I'm going to bed just go on Tim Sweeny's Twitter or use any of my links.

[_dangerclose_]

Turns out you're still bitter that demo was running on PS5. Grow the hell up and let it go Elsa.

[Kyizen]

You believe everything coming out of China? Haha

[OB1Biker]

The PS5 demo can run higher than 30fps it was just locked. They played a video on a laptop here

[gravedigger]

Not exactly. Looks like plot got a twist. Chinese dev ran originally PS5 demo on his laptop :

https://twitter.com/iamalit...

Of course you can run an .mp4 file on a laptop. Even Sweeney said something about this :

" They playing the video on the stream. Do you see the ".mp4" in the title bar?"

https://twitter.com/TimSwee...

"I think people were confused by an event where the VIDEO was played on a laptop."

https://twitter.com/TimSwee...

Btw.resolution by this chinese dev. WASN'T SPECIFIED. He only mentioned 40+ fps

https://forum.beyond3d.com/...

Demo could scale to other platforms it doesn't mean every setting is going to be the same or run the same because of it. Sweeney already said this will scale down ( depending on specs ) it just won’t look as good.
Nanite and Lumen requiring good I/O SSD output. And PS5 can deliver that.

[OB1Biker]

I dont know why people are so dense. They said many times its scalable. They can just reduce the level of details for other platforms.
UE5 will run even on android.
In this case it was just a video though.

[umair_s51]

I think for next gen ps5 will be the weakest link

[sampsonon]

Epic games china? lol how about sweany himself https://youtu.be/VBhcqCRzsU...
So enjoy the bone Epic China gave you lol. So yes it will play on any pc or Phone. But they would need to scale back in order to run it.

The ps5 demo was running with 8k textures.... guess what 1440p is doing?

The only good news here is that the engine is scalable.
Obviously, high end PCs, the ps5 are known for what is going on in the demo.

The scale down part is the tell of the ignorance levels in this troll of a post.

Yup

Sony a multi million dollar company is so dumb they spent millions developing their ssd solution.
they should have just slapped together powerful parts like microsoft and they could have easily won next gen.

Let me tell you when i'm reading all about the magic stuff SSDs can do i think wow how many PhDs in ignorance we have here someone got to say something but then i tell myself man let it roll toward that wall facts are facts in the end of the day no matter what they do or say.

[seanpitt23]

This got debunked haha the laptop was just playing a video of the demo couldn’t actually run the demo.. pc elitists are trying there best..

turns out where??
show us the pc demo , not an appeasment statement from an ex pc games producer...

[XxINFERNUSxX]

Didn't this shill Tim Sweeney say it can't run on PC? If so that's some marketing BS right there. Anyway lets try a 2080 ti and also next gen RTX cards are coming with a rumored RTX 3080 with a possible 21 tflops. UE5 4k 60fps will be pretty easy with that kind of GPU :D

[on_line_forever]

Don't forget ddr 5 ram

[Ceaser9857361]

Cant imagin the price for RTX 3080 which most pc gamers wont be buying... but ya 4k 60fps would be amazing.

I'm waiting for the 3080ti

[Movefasta1993]

why do you worry about what other people spend their money on? Are you the type of guy to make fun of someone who owns a McLaren f1 because only a few people have it?

[Movefasta1993]

They keep making these high end graphic cards yet nobody buys them right? why keep making them... LOGIC.

[Unspoken]

If AMD continues to push on the GPU front prices should theoretically prices should come down for the 3000 series. Then again it's nVidia.

[Ceaser9857361]

Oh it doesnt bother me what other people buys. They can do whatever the hell thy want. My response was to that guy who brought up rtx 3080 (didnt even got announced )could handle it when Tim said PS5 ssd is superior then current gen pc. Infact alot of pc players are genuinely butthurt and most boast about specs they dont have, so ya most wont be buying a 21tf cards for GAMING since it would be expensive. May be few would buy it and say Look my PC is more powerful then console where the price between the two will be a big difference. Unless Nvidia is kind enough and sell the 3080 3080ti for cheap like 200 USD lol!

[starchild]

Yep, DDR5 memory, PCIE 5.0 and the increased bandwidth it offers for new graphics cards and faster NVMe SSDs, AMD Zen 3 processors, Intel Rocket Lake S processors (finally a new Intel architecture)...all of these leaps forward are coming within about a year. Pretty exciting stuff happening in the PC space, along with the new consoles.

[Profchaos]

Tim Sweeney tweeted earlier this demo did not run in real time on the PC it was simply played at an event as a video on the device that same way we all watched it on YouTube

Because it wasn’t compiled for PC?

[Babadook7]

Here's the real story... https://twitter.com/TimSwee...

And https://twitter.com/TimSwee...

[rainslacker]

It probably exists on PC. Unreal builds easily to PC for testing purposes. To my knowledge, they havent released a PC build of the demo to the public though.

We do know the demo they showcased was captured from a ps5 dev kit.

The chinese thing seems to just say that a pc can run the demo, but there are conflicting reports about the translation, and sweeney seems pretty adamant about it requiring at least what the ps5 offers in terms if SSD throughput.

I'm prone to side with sweeny on this, but I'm willing to accept that it can run on PC with a suitable SSD installed. There are still some unknowns with the SSD implementations of what they were showing in the demo for me to make a twchnical.judgement on what would be required, and honestly, I dont think it's worth the time to really try and figure out.

[Profchaos]

Tim Sweeney tweeted that they had just played the video on the laptop not actually run the demo in real time the system did not run it.

It's the same as me watching it in my three year old android phone and claiming my device can run the demo

[shiva1]

They why is Sweeny up late night answering on twitter? He could have just said we dont have epicness in China and there is still no PC which can run this demo in China.

[Babadook7]

Nice conspiracy theory.

[tontontam0]

Everything with "CHINA" slapped on it is untrustworthy in these troubled times.

[Chaos-Dad]

Tim Sweeney on Twitter:
"I think people were confused by an event where the VIDEO was played on a laptop."

[Babadook7]

Yup. And.

Tim Sweeney on Twitter:
"They playing the video on the stream. Do you see the ".mp4" in the title bar?"

The thirst is real from the PC crowd. lol

[rainslacker]

The Xbox crowd seems more invested in this matter than the PC crowd.

Sweeny seems more intent on pushing forward the minimum standard on PC to include high speed, or even standard SSD drives, more than he is interested in fighting a console war that tries to position Sony above MS. PC is where they make most of their licensing fees for UE.

He never said it couldn't run on PC. He said that with the way the I/O setup is today, and the standard not including something equivalent to SSD, it wouldn't be a reliable way to design a game around the features from the demo that used SSD tech as a best practice paradigm like they have on the consoles.

[Babadook7]

@rainslacker

We don't know if any consumer PC can run this demo as is. And that is because the PS5 has many customizations beyond what consumer PCs have. Thats all well known by now. Sweeney is going to pick his words carefully however, because ultimately they want their engine to run as many places as possible and to keep relations up with Microsoft and all developers. Judging by what Epic has said, PS5 was the best way to show off this tech and Sony deserves due credit for that. I'll leave it at that.

[Edgelordsupreme]

Oh please, if you don't think UE5 is designed with the PC in mind you need to stop talking.

[rainslacker]

All I think is that sweeney seems really intent on pushing the minimum PC spec forward. The thing about the demo, is that it was built around showing off SSD speeds and what it could do for gaming. GPU advancement is a given, and all.it would change is the quality of the visuals. But the more important thing is the loading of assets at a minimum required speed.

I'm sure the demo could run on a properly spec'd machine. What seems to be in contention is what is considered the minimum spec for hard drive data transfer. PC may require a bit more speed due to the nature of PC OS handling data transfer, which adds overhead to get it from the hard drive to memory. Unfortunately, DMA on GPUs still has to process its request through the OS, then be given permission with restrictions, which is an added step. When this stuff may have to be done super fast, the more overhead, the more restrictions it puts onto what can be streamed, meaning more consideration given to how to build the worlds.

[Hungryalpaca]

Tim also said this would run fine on modern SSDs.

But keep it up. You’re sitting right beside the power of cloud people.

[MWH]

Kid, you must be out of your damn mind if you truly think this demo cannot run on a modern PC. I don't care what they tell you, believe it only when you see it and until then keep your excitement levels on check and stop spreading bs.

[nismo370]

What kind of mp4 VIDEO needs a 2080 to play at 40fps?
They never ran the tech demo live on laptop but they said that their laptop with RTX 2080 and less demanding SSD can run it on 1440p and 40fps when they were testing it in tech Labs. Tim wont reply to this but it would be interesting.

[tagzskie]

If rtx 2080 cant run it at 4k/60fps with out sacrifice then i really doubt next gen console can run it. Not unless the developers have a better optimization technique. Sony developers really good at it seeing ghost of tsushima on base ps4.

[plmkoh]

4K has been a total disaster since the industry attempt to move past 1080p.

1. Soon to be 3 generations deep of graphics cards 'designed' for 4k and 60 FPS is still in catch up
2. And even then those prices are out of reach from the mainstream, my 1080ti has a ridiculous 2nd hand price
3. HDMI be like 1.4b nope....2.0 nope.....2.1 almost ready when those 2yr old 'ready' devices can be any readier

I mean sorry, am I suppose to feel better if I bought a $3k RTX2080 based laptop to just run a game in 40fps?

[rainslacker]

The whole 4k spec in general has been one big clusterF of standards and disparate roll outs which caused delays in implementation, and added to frustrations of those early adopters. Its settled down there now, but the idea of 4k is negotiable when resolutions between 1080 and 4k often provide results which can be indistinguishable to the end user.

[WheatBread]

The notebook version of the RTX 2080 is slightly faster than the desktop version of an RTX 2060.

Just sayin

[Babadook7]

Can it run an mp4 though?

[Kribwalker]

yeah. It can also run the ps5 tech demo better than a PS5

[ApocalypseShadow]

Lmao. Sony has got everyone bent out of shape. Except for Nintendo fans of course.

PC elitist crowd and the Xbox crowd. Just foaming at the mouth. On a multiplatform engine that will run better or worse depending on the hardware you got.

First it was freaking out about Mark Cerny's GDC inner workings of PS5. Like the Tempest Engine. And now, Epic premiering their next Engine on PS5. Because they didn't pick PC or Xbox.

"Well, we're more powerful." "How come they didn't choose us?"

Tim already answered the question. Got you guys scared with fear. Like Damn. Just cracking me up.

[Felix_Argyle_Catbro]

They made a deal with Sony. That's why. They have the marketing deal. It's very simple.

[sinspirit]

Sweeney said there is no secret deal on Twitter. Just debuted the engine on PS5 because of Sony's involvement with the tech and their PS5.

[sampsonon]

Yeah, Sony and Epic built both together. Smart.

[generic-user-name]

Why would Epic need Sony money when they have Fortnite money? Why wouldn't they show UE5 running at it's absolute best on an Series X unless that's not where it runs best?

Think about it.

[StarLink]

More like its got PS fanboys like yourself desperately grasping at straws and making sh*t up just to push a false narrative and as it turns out we were right and you where wrong. Deal with it.

[sampsonon]

yes false lol https://twitter.com/TimSwee...

https://youtu.be/VBhcqCRzsU...

[SegaGamer]

All of you fanboys are as bad as each other, so I don't see how you can talk.

[ApocalypseShadow]

Pot meet kettle.

Hi kettle.

[SegaGamer]

@ApocalypseShadow.

Since when have I ever been a fanboy? You on the other hand, you are ultra defensive about any tiny piece of shade thrown at Sony and you are on every Microsoft article playing down anything positive. Seriously, it's pathetic. You aren't the only one though, there are tons of you, and you make this site unbearable most of the time. You are grown men and women, probably over the age of 30, and you white knight for companies that are only interested in taking your money. How do you not see how pathetic that is?

[ApocalypseShadow]

Still cooking soup in that kettle I see.

No. it's losers like yourself who don't like facts about Microsoft and their screw ups. Don't like the fact that we point out their laziness to make games but are worth a trillion dollars but can't keep up with Sony or Nintendo with less money.

You don't like that we support the other two because they aren't trying to screw over the console industry with services and removal of game ownership. Go sit in the corner and cry about it. I will continue to point out their failures.

Epic presented a new game engine. Sweeny said why they did it. But you guys want to lie about Sony paying money or are worrying about its use when every console and PC will use it in their own way. But you want to tear down the presentation because Microsoft failed at showing what next gen is about.

Have a tissue.

[SegaGamer]

"No. it's losers like yourself who don't like facts about Microsoft and their screw ups"

I never actually said that. I have criticised Microsoft plenty of times over the years on here, so that is complete horses***.

"Don't like the fact that we point out their laziness to make games but are worth a trillion dollars but can't keep up with Sony or Nintendo with less money.

I couldn't give less of a **** about any of that.

"You don't like that we support the other two because they aren't trying to screw over the console industry with services and removal of game ownership"

Again, I never said that. Also, you don't support, you fanboy, there is a major difference. The way you go ultra defensive about literally ANYTHING negative said about Sony, and the way you criticise any news about Microsoft shows that you are a fanboy. Also, don't pretend that you support Nintendo, because you don't. If there was a single article that was to praise Nintendo and throw even a tiny bit of shade at Sony, you would be on it in a shot going ultra defensive in favour of Sony, like you always do.

"Epic presented a new game engine. Sweeny said why they did it. But you guys want to lie about Sony paying money or are worrying about its use when every console and PC will use it in their own way."

Again, I never said that. What is it with you and making s*** up? I haven't said anything at all on here about that tech demo. Why would I care that much? it's just a tech demo. The way you fanboys have reacted to this tech demo is pathetic.

"But you want to tear down the presentation because Microsoft failed at showing what next gen is about"

To finish off, you make s*** up again, what a shocker. Whatever and whenever Microsoft show next gen stuff will have very little interest to me because I won't be buying their next console anyway.

[ApocalypseShadow]

Then you could have kept your mouth shut about my comment or skipped over it. It's easy to ignore. I really don't care what you buy.

The only thing I'll present in these comment sections are either facts or a joke. Not fanboy nonsense. I don't spew lies like some Xbox fans do. And I'm not an elitist worried about who has the most power. Because power isn't everything. Nintendo has proven that again and again. Even against Sony. And Sony has proven for 25 years that quality games is all that matters. Not hot air and promises while spending very little of that trillion dollar worth. I only care about who's making quality games and are pushing the console industry forward without robbing gamers.

Epic presented an Engine. And gamers are bent out of shape because they used Sony's SSD. Then believing a Chinese site that ran a video and dummies jumped on it. Then Tim had to say again why they used Sony again. Because idiots don't read or listen. Not saying you. Same happened with Cerny. He had to reiterate what was said because idiots don't listen.

Don't like what I say, ignore my comments in the future.

[airshiraz]

so we can have 1000 times more polygons than ps4 ?rubbish

[FlyingFoxy]

https://www.youtube.com/wat... Laptop GPUs are often weaker than desktop equivalents.

[xX1NORM1Xx]

Anyone who thought that demo wasn't possible on pc is an idiot...

That test was impressive because it's on a console at a price point below that of a pc with an RTX 2080.

Edit- technically we don't know the price but I guarantee it will be lower based on the fact that Sony and Microsoft can get cheaper per unit cost due to scale.

[Fritzwochel]

WELL. The PS5 demo is capped on 30fps. We need some better benchmarking to compare. It could go higher than 30.

[sampsonon]

no it couldn't https://twitter.com/TimSwee...

[tontontam0]

It is starting to be a PR disaster for sony.
I hope sony is not dumb enough that they paid epic to showcase ue5 if the engine runs better on xbox series x.

[Pricey]

Erm... It was a video. https://twitter.com/TimSwee...

Nice try

[Sophisticated_Chap]

The RTX 2080 Mobile GPU is roughly 10-15% less powerful than a desktop RTX 2060 Super, and it's running the demo at 10FPS more than the PS5? It's going to be interesting to see the Digital Foundry videos(for PS5 and Series X), and see if RDNA2 actually does finally match Nvidia Tflop performance. If this statement is anything to go by, its not looking very impressive for RDNA2 at the moment.

[sampsonon]

Already been explained https://twitter.com/TimSwee...

[pitythefool]

Man, this demo being shown on PS5 really has got some people bent outta shape, breathe in, breathe out, you’ll be fine.

[waverider]

They are scared....

[Edgelordsupreme]

Its a video game console you dullard. What is there to be scared of?

[Hungryalpaca]

Scared of what?

[Einhander1971]

Here we go again, arm chair game designers and hardware engineers. You all no shit and just speculating as usual. The demo looked amazing if next gen looks that good we should all be happy. Regardless of which damn system it’s running on.

[Starman69]

Well said bro!

[MrVux000]

Um,didn't Tim Sweeney clear this up already?

[sampsonon]

YES https://twitter.com/TimSwee...

[Rimeskeem]

So it is just under a RTX 2080 in framerate basically. The Xbox Series X supposedly has the power of just under a 2080 ti while but with a significantly slower SSD while the PS5 has a super fast SSD but only the power of just under a 2080. Both systems have hardware dedicated to ray tracing but the PS5 also has the tempest engine.

At this point I think the consoles will be around the same price at launch I am guessing. PS5 might be a bit more due to the SSD and tempest engine tho.

[Pricey]

They don't like the truth lol :)

Damage control.

All i can say is 'trump' ( it came from chynaa ) :-D

[OB1Biker]

It's actually hilarious to see who is falling for this.

[Games1st]

If a pc can do it, then it didn't make much use of the PS5. This is just a snack before the main event.

[sampsonon]

https://twitter.com/TimSwee...

The series x is Elvis and the ps5 is boy George

[sampsonon]

HAHAHAHA!!!! https://twitter.com/TimSwee...

[Imalwaysright]

You're really spamming this thread with that BS.

[generic-user-name]

Got any proof that Tim Sweeney is lying? Why should I believe you over him?

[Imalwaysright]

Sweeney is talking about the video, he isn't debunking what Epic's engineer actually said and according to people that unlike Sweeney do speak mandarin this is what he said:

https://pbs.twimg.com/media...

What Sweeney is doing is nothing but an extremely weak attempt at doing damage control that will only fool those that want to be fooled just like the spammer above.

[OB1Biker]

Did you even read the first sentence of the link you posted?

They talk about the first scene and its even downscaled...
Really much ado about absolutely nothing.

[Imalwaysright]

Yeah you should read more than the 1st sentence. Also, the demo clearly wasn't as optimized to run on his notebook as the demonstration on the PS5 obviously was and still his notebook with a mobile gpu was able to run it at 40 fps.

[caddytrek]

And this article is why random language articles shouldn't be allowed. Anyone can take a Chinese video and translate it into anything and no one can verify what is being said. At best this should be a rumor, and as a rumor it should have been failed.

[GordyNYC]

Its all about that retro cartridge-like experience!

[frostypants]

It's a $650 GPU so I'd hope so.

[waverider]

This Was already told that is fake, but look at the Microsoft 'gamers' here... How sad can You go. After this week... Damn, i really cant understand... They never, never ever learned.

[richie007bond]

Gaming Tomarow

Eurogamer.net article

Your welcome

Our second component is a high-speed hardware decompression block that can deliver over 6GB/s," reveals Andrew Goossen. "This is a dedicated silicon block that offloads decompression work from the CPU and is matched to the SSD so that decompression is never a bottleneck. The decompression hardware supports Zlib for general data and a new compression [system] called BCPack that is tailored to the GPU textures that typically comprise the vast majority of a game's package size."

[waverider]

Secret sauce, wont work dude....

[generic-user-name]

Already debunked, but amusing to see so many desperate to believe it.

[kayoss]

All sudden the experts come out from under the rocks to comment. Regardless, Sony's first party game studios have a history of using the console at its fullest potential. If you argue with that fact, your'e and idiot. Sony first party have known to push the consoles to their limits and have shown us that regardless of what the specs on the console is, the first party studio will use every ounce of power available to them.

[Passerotto]

Fake, but......why not?

[SamTheGamer]

This is what Tim said... https://twitter.com/TimSwee...

[Father__Merrin]

just to remind everyone a 2080 equipped notebook is around the £2500 mark!!!

https://www.scan.co.uk/shop...

[kryteris]

odd considering the 5700 has similar performance. Also someone in comments keeps saying that tim stated that was just a video on the laptop.

https://www.notebookcheck.n...

[brrdat]

Where did Epic claim this?

[MrSec84]

They lied, it was running the video, Tim Sweeney confirmed it on his Twitter.

[SamTheGamer]

Here https://twitter.com/TimSwee...

[MrSec84]

@SamThe Gamer:

Yep.

[nismo370]

So why did Epic China mention 2080 SSD and 40 fps? DO YOU KNOW A MP4 VIDEO THAT REQUIRE A 2080 AND RUN AT ONLY 40 FPS????
Tim Sweeney = DAMAGE CONTROL.
Read the tweet from the chineses, and think...

[MrSec84]

https://twitter.com/TimSwee...

Sweeney's words taken from his Twitter:

"The are running a VIDEO PLAYER on that laptop, playing a video of Unreal Engine 5 running on a PlayStation 5."

[Profchaos]

Unfortunately no one will actually see this retraction and the internet will believe this for the next five years

[MrSec84]

Articles should be covering Tim saying that those guys aren't representing the whole truth.

[Profchaos]

Absolutely articles should be covering the truth this article should be flagged as rumour the source is dubious at best try to go to the site the information was originally published and it's just not there anymore.

But it doesn't fit the narrative if the console war so that's the last we will hear of it.

[waverider]

Dude, the lack of brain of some is just incredible. Slower ssd and gpu on a laptop runs better. This makes perfect sense. Damn, the desperation of some is getting through the roof.

[nismo370]

Damage control.

[MrSec84]

Link to where this Chinese video of a RTX 2080 laptop is running the demo natively in real time or a dev that is actually working on the engine has said those specs can actually run the demo at that level.

People are getting hung up on the 40FPS thing, when Tim Sweeney has already talked about the overhead required to maintain a locked 30FPS when the frame rate is capped.

[chiefJohn117]

Not surprised, but it was still a great marketing move by Sony. Got the fanboys pumped up

[GamingInFrames]

So now 1440p/40fps is something to bragg about... go figure.

[itsmebryan]

No, it just shows that PS5 is not the only thing that can the demo. As if XSX or anything thing else was not capable. It just proves that even a laptop can run the tech demo 10 fps faster and XSX will probably run it better than PS5 because it is more powerful.

[anubusgold]

Linus tech tips called Epic games a Liar Asus and several other SSD makers have SSDs that are 15,000MBs so yeah epic is stuck on slow intel motherboards. Its starts at the 22:00 min Mark https://www.youtube.com/wat...

[Destiny1080]

its not about the speed of the SSD you could have a 50 million speed SSD but if it runs into bottlenecks all its speed is gone, mark cerny eliminated the bottlenecks associated with SSD Architecture

Pc will get around this by Adding SSDs Directly to the GPU for lighting fast speeds there already in the making by AMD and Nvidia

[anubusgold]

Amd already did that putting a ssd on a gpu.

[anubusgold]

No a PCie 4.0 ssd in a Pcie slot 4.0 will run fine there isnt a bottleneck actually they cant even fill it. The only bottleneck is Intel computers that dont have pcie 4.0

[isarai]

This comment section is f#@kin hilarious given it turns out that was just an MP4 video playing on the laptop.

[nismo370]

Epic Games developer
“Our goal is that the graphic quality like this demo, we want to make it run 60FPS at next-gen consoles. But now we do not reach the goal. Now it is 30FPS. Our target is 60FPS, that is also why we can not release it now. And I can assure you that we can run this demo in our notebook, in editor , not cooked, it even can 40FPS. (Afterwards someone in BBS confirmed that the device is RTX2080 and 970EVO)”
So why did Epic China mention 2080 SSD and 40 fps? DO YOU KNOW A MP4 VIDEO THAT REQUIRE A 2080 , a fst SSD AND RUN AT ONLY 40 FPS????
Tim Sweeney = DAMAGE CONTROL.
Read the tweet from the chineses, and think...

[isarai]

If you watch the stream it literally says .mp4 in the top bar aswell as still has the Playstation buttom prompts. Again, hilarious.

[Donnie81]

So what they are saying is what all the other developers and experts have been saying the last few days. The more powerful system is gonna run it better. The ssd isn’t gonna magically make up for all the systems shortcomings vs the competition. Smart move by epic China they know at the end of the day Xbox is one of their biggest customers and they wanna keep it that way.

[generic-user-name]

How well is the X1 selling in China?

[Donnie81]

How does that apply to what I said? Epic could care less how the system sells they get their licensing fee from Microsoft upfront. They may take a cut from game sales on smaller devs but Microsoft that’s not doing

[generic-user-name]

You're right it doesn't, I misread your comment, my bad.

[Donnie81]

No problem dude I do it all the time. :)-

man this rains on a certain group of misinformed fans parade. Xbox hype!!!!

[FlavorLav01]

$1200-2000+ new gen cpu/gpu gaming laptop should perform as well as a $500 box. Is this a surprise? I can see PS5, SeriesX, and PC trading performance blows all next gen depending on the game and optimization priorities chosen. Gonna be interesting.

[Tedakin]

Do Sony fans honestly believe this demo is not capable on anything but a PS5? A PS5 is more powerful than any gaming device ever created. More powerful than a 5000 dollar gaming PC? You guys really seems to think that.....

[itsmebryan]

Yes, they do. Lol

[Voodoopower73]

That's a fake story. Sorry to inform some people.

The actual laptop running the Demo was infact a video file running it at 40fps.

Tim Sweeney has already clarified this.

Obviously the engine was be on all systems.

[anubusgold]
