Unreal Engine 5 Nanite Tech Can Easily Render a Million High-Poly Objects at 60fps on PS5

Just how many thousands of objects and billions of polygons was that Unreal Engine 5 demo pushing? New details on Epic's next-gen tech!

[Jin_Sakai]

A million high-poly objects at 60fps sounds amazing. Can’t wait.

[GamerRN]

Would be nice if it could do it at 4k...

[RazzerRedux]

lol....why? DF had to use Photoshop magnification to tell the difference between a lossless 4k image from the UE5 demo and its corresponding 1440p version. Why waste processing resources for differences your eyes cannot detect?

[GamerRN]

@RazzerRedux

I can see the difference between 4k and 1440p on my 82" tv. I sit about 6 feet away and can see the difference... Also, if a competing console decides to use the same reason as PS5 it could actually outperform it and have higher poly counts. So the point is it's a weaker system

[CBaoth]

We're not talking normal 2K vs. 4K. The UE5 demo used a form of temporal aliasing that rendered a 1440p image indistinguishable from 4K. The chaps at DF had to zoom to 400% to notice the minute differences in the upscaled image versus the native one. I seriously doubt with out this, ray tracing would even be possible on the next gen consoles.

EDIT: at least not without serious concessions

[GamerRN]

@CBaoth

It's not ready tracing, it's a ray traced lighting lighting alternative. Please don't confuse the two.

Also XSX has dedicated ray tracing hardware. It's very doable this coming generation on that box

[Kribwalker]

Then why didn’t it?

[Jin_Sakai]

If you’d read the article you’d know.

“The “Lumen in the Land of Nanite” demo ran at approximately 1440p and 30fps, but apparently, the PS5 could easily render most of it at 60fps. As we already learned, Nanite is not particularly taxing on hardware – the entire GPU rendering cost of the demo was about 4.5ms, which is about 1/4 the timeframe budget at 30fps or 1/8 at 60fps. The demo also only used a rather paltry 768MB of RAM.”

“Lumen is the reason the UE5 demo only ran at 30fps, although Epic is hoping they’ll be able to get it working at 60fps”

[Kribwalker]

i did read it. If you got rid of lumen, then it would run at 60fos, but without lumen, it wouldn’t look as good. So why are they having to sacrifice? Lumen is like a type of software ray tracing per say. It’s not genuine ray tracing, and if your hitting 1440p/30fps with kinda ray tracing, what’s it gonna be like with full ray tracing

[sinspirit]

@Kribwalker

Ray tracing is ray tracing. What do you mean not genuine? Software just means it's not taking advantage of dedicated purposed hardware or accelerators. It's still ray tracing.

[Babadook7]

I think there is a misquote there. 4.5ms is 1/4 or 60 fps budget and 1/8 30 fps budget. The demo was on both early PS5 hardware and an early engine prototype so its possible their goal of 60 fps is reachable.

[GamerRN]

@sinspirit

It's not ray tracing, it's a cheaper alternative

[sinspirit]

@GamerRN

Ray tracing is ray tracing. Any ulterior method of lighting isn't ray tracing or labeled as such. If it's ray tracing, then it's ray tracing. Ray tracing is a very specific method of light rendering. Explain how it's a cheaper method. The only difference between software and hardware is that it's not running on dedicated ray tracing hardware or ray tracing cores. Software actually is historically and technically more accurate than hardware for rendering, but it takes far longer to get results and the difference is unnoticeable.

Absolutely ridiculous that people make up these remarks on the spot or twist heresay that others have told them to try and join technical conversation.

[Tech5]

@ Kribwalker

i would imagine they're still working on it and it won't be out till late next year.

----------------------------- -----------------
on the side -

the engine no doubt will be even more powerful. though even with that said, even with these new tools. considering that not all developers will be the same. you may still have other factors to consider for game development. - budgets, pricing, ambition, team scale, and project scale. we will have to see how many developers will be producing the content at the standards.

[blackblades]

The engine is still in development bruh

[IRetrouk]

Good to hear, one of the epic devs talked about it outside of the video on twitter too.

https://mobile.twitter.com/...

[JEECE]

Wait, you mean a tech demo of a new engine, shown half a year before a console launch, was not a demonstration of the engine's full capabilities on that system?

[silenthillstrangler]

Lets hope they are able to, it would be a shame to spend another console gen in 30fps.

[Christopher]

Let's be honest, current-gen is only in 30fps because of the prioritization of graphical fidelity over performance. If that holds true next-gen, then it won't be because 60fps isn't possible but because they prioritize graphics over everything else.

[Modestmex]

i didn't read your comment Christopher basically the same comment that u stated.

[silenthillstrangler]

Though their is far more room to have both this gen unless its ubisoft.

[RazzerRedux]

@Christopher

Exactly correct. I see folks talking about a system that "targets 60fps" and such. Any system can "target" 60fps. It is a sliding scale between fidelity and frame rate.

@silenthillstrangler

Sure....if they were trying to maintain current gen visuals and focus on frame rate, but that isn't the case. Last gen it was the race to higher resolutions. This gen it is about enhancements like ray tracing.

This is why we should have modes like what they will have in the Demon Souls remake. Let gamers decide over visuals vs performance.

[Modestmex]

lets be honest these consoles are always gonna be pushing fidelity to high levels so they gonna have to sacrifice performance. you want pretty graphics and 4k.

[silenthillstrangler]

1440p, dynamic res, upscaling, all ways to achieve both performance and fidelity.

[Einhander1971]

The ps5 will be a beast.

[GreatSako2020]

So as per the video, PS5 30 fps was because or Lumen and they said they are optimizing it to run on 60 fps

[airshiraz]

i think they r not bluffing and that good news

[shiva1]

When is confirmed release date of UE5?

What games are confirmed with UE5?

[garos82]

not confirmed yet for release date but supposedly late 2021

[Felix_Argyle_Catbro]

I'll believe it when I see it.

[buffig]

There's no reason why not. At 4k, it only needs to render a polygon per pixel. That's 8.7 million. Even if the models in the scene have billions of polys. It's the way the engine streams and adapts the data which makes it so impressive

[buffig]

That's because the engine scales geometry so well. It can render a triangle per pixel. Anything below that size is unnecessary as it can't be seen. So even at 4k, the engine will only ever be rendering a maximum of 8.7 million polys. Even if there are 10 billion polys in the scene. It's simple but groundbreaking and why that SSD is fundamental.

[Smclaren1985]

Fantastic 👍 I seen this on YouTube the other day as well. The tech demo on ps5 was able to hit a consistent 45 FPS at 1440 p upscaled through TAA. They locked it at 30fps . Then they announced they where targeting 60fps and believed they could achieve it now they have had time to optimize and tweak as well as Sony updating the dev tools regularly too. This is epic news 😂lol

[JEECE]

I'd so be in favor of 1080p 60fps over 1440p 30fps if it comes to that, although hopefully it doesn't.

[Smclaren1985]

I would prefer 60 FPS too it’s night and day diff . But at the same time I don’t want just 1080p I recently bought a 60 inch 4khdr tv lol I want min 1800p next generation. I would be really annoyed considering nearly every game on the Xbox one x I have are 1800p the PS4 is often 1440 p I’m so used to it no it’s night and day compared to 1080p.Come now 1080p that’s really not worth it it’s next generation man lol I wouldn’t mind 1440p 60fps with the bells and whistles but I would expect the resolution to be a little higher than that. They seem very confident mind you . What really gets me is developers touting 120 FPS it’s a a stupid thing to claim . 95 percent of tvs on the market don’t support that so no developer wont waste time on that in general. You’ll get the odd one here and there and it will likely be 1080p drastically paired back visuals

[Ash01Live]

Ok cool. Don't just talk about it, make all UE5 games 60fps. Make it so.

[Ash01Live]

I wish devs would stop pushing 'true 4k' look at death stranding with dlss at 1440p internal resolution, superior image quality and almost double the performance.

[Smclaren1985]

It’s not superior there is flaws apparent throughout its better than DLss 1.0 eventually they will get it looking perfect but it can never be a superior image esp if it was on a large tv you can see it a Mile away

[Modestmex]

At what resolution? 1080? since was running at 1440 30fps

[Pyrofire95]

Yeah so stop targeting 30fps pleeeease. Let 60 become standard again.

[Smclaren1985]

I agree but they have came out and said there now targeting 60 FPS and believe they can hit it as the demo could hit a steady 45 but they capped it that was without proper optimisations

[mark_parch]

Why didn't it then?

[Smclaren1985]

Because it hadn’t been properly optimised yet plus Sony’s dev tool set wasn’t finalised yet so improvement come naturally from both ends they feel pretty confident now there targeting 60fps. They also confirmed the fgpu usuage was very low during that demo also

[Father__Merrin]

Just wait for the games to come out and watch their heads real in back to humble bundle indiegala fanatical

[ASSASSYN]

That just means it will do it even better on series x and pc.

[Imortus_san]

Next gen is 4 month away, so you better get your act togheter EPIC, I want quality and 60fps.

[garos82]

next gen is 4 months away but epics newest engine will only be available next year. they have plenty of time to polish

[Smclaren1985]

Ue5 isn’t launching untill the end of 2021 so they have more than a year of optimizing
