Performance of Next-Gen Effects on Xbox One Detailed; PS4 Can Do Volumetric Fog Asynchronously

During the panel “Assassin’s Creed 4: Road to Next-gen Graphics” held at the Game Developers Conference Ubisoft Montreal 3D programmer Bart Wronski gave some quite interesting information on what it took to launch Assassin’s Creed IV: Black Flag on next generation consoles, including some detailed information on performance costs of advanced effects like volumetric fog and screenspace reflections on Xbox One, also mentioning that the PS4 can do the former asynchronously.

What does this mean....also what is the purpose of mentioning the ps4...

Before commenting u should read the story the ubisoft guy is talking about the xbox one....then the author says that the ubisoft guy didn't give any charts about the ps4 or was talking about the ps4...he was probably asked about which his response was that it could do it to....also the author then adds that the ps4 can do Ray tracing after it is mentioned the xbox one can do it....and then goes on to give an example on ps4 (killzone)....I'm just saying why was all that needed why couldn't the article simply be about the presentation

@ incendy below

Okay thank you for clarifying...I still don't understand but I think what ur saying is it allows for more things to be done without putting more stress on the Gpu which allows the system to do more things....if I'm understanding u correctly if not it's okay I probably wasn't going to get it anyway...but thanks again

Abriael1518d ago

Let's see... because it was part of the presentation and the fact that it can compute the effect on the GPU is interesting?

I know, hard to understand right?

Lawboy21518d ago (Edited 1518d ago )

No it wasn't...they added I in...did u read the story

Well good now that I'm talking to u...what was the point in pointing out the ps4....if u have no slides or he was specifically using the ps4 to demonstrate it why mention it...I understand telling the ps4 can do it...but to go into detail about the ps4 without it actually being what it is shown on escapes me...maybe I don't understand it just seems like it was away to not let the spotlight shine on the xbox one

Okay sorry for all the edits

I just read the presentation...I was confused by the article...sorry @ abriael....the presentation was for both xbox one and for ps4 combined it was just shown on the xbox one...I didnt get that at first sorry man...

Abriael1518d ago (Edited 1518d ago )

@Lawboy2: Not only I read the story. I *Wrote* it.

PS4 was mentioned extensively in the presentation, including the asynchronous compute feature, and for the second table it was mentioned that the 2ms timing is for both consoles.

This is where Sony's heavy focus on GPU compute is paying off. Sony put 8 asynchronous compute engines in PS4's GPU, vs. only 2 in xbox one. Each ACE can have 8 compute queues each. So, Xbox One can handle 16 compute queues at once and PS4 can do 64. This is why PS4 is shown to have the advantage here. The GPU can use all those ACEs to do things like volumetric fog, lighting, physics, fluid dynamics, etc. without being a performance drain on the CPU or other elements of the GPU.

Asynchronous means that the effect does not hold up other processes and is possible that it is not run in order of first to last. Basically you don't have to wait for it to finish, it will do its work without holding up any other tasks. It is mostly a good thing, you can always run a task synchronously if you need to.

scott1821518d ago

The asynchronous compute feature takes stress off of the GPU to do features like volumetric fog? Am I understanding right?

Angeljuice1518d ago (Edited 1518d ago )


It's kind of the other way around, the GPU does the computation itself without having to wait to communicate with the CPU, thus speeding up the process and freeing up CPU resources.

xx4xx1518d ago (Edited 1518d ago )

I don't know either.

But if it's on, you can bet it's:

PS4 = good
XBox = bad

-Foxtrot1518d ago (Edited 1518d ago )

Really so your going to list a site as a fanboy site because of what they REPORT on. It's not their fault if theres "bad" Xbox news out there then PS4 news

If you want a bias site look at Polygon.

Muerte24941518d ago

lmao oh the click, hungry Polygon.

FamilyGuy1518d ago

Dualshockers... is called Dualshockers. With that name you would think it to be a more Sony focused site to begin with. Aside from that I've seen some X1 articles there that were positive, there just isn't as much positive news about the X1 when compared to the PS4 or all the negative X1 news.

MasterCornholio1518d ago

Its their fault that the Xbox One is weaker than the PS4. Which is why developers announce more advance graphical features for the PS4 like dynamic clouds in MGS5 Ground Zeroes.

cell9891518d ago

for biased websites look up in your dictionary POLYGON, youll see biased there

Holy crap, seriously?

It was an Assassin's Creed panel, not an Xbox One panel. BOTH CONSOLES were mentioned, hence the purpose of mentioning the PS4.

It cannot be that difficult a concept.

Why is the PS4 even mentioned in the headline on an interview that is about the features of the Xbox One? Yea, Dualshockers, you sure know how to get hits.

Abriael1518d ago

Here's another that didn't even read it.

One. It's evidently not an interview.
Two. The presentation is about both consoles. The Xbox One was the only one for which precise timings were given, but the PS4 was definitely included.

My, so defensive.

No_Limit1518d ago (Edited 1518d ago )

My apologies. I read a bit through that long PDF file and there is a bunch of stuff on there pertaining to all systems but the way you presented it on your website by picking and choosing certain parts to quote and the way the headline is constructed really adds fire to the flame, so to speak. It would be better if you just separate those two topics and post them separately.

Sci0n1518d ago

what im getting from butthurt xbox fans is they want all news and things said about the xbox one to be neutral with the PS4 or not mentioned at all. The thing is we can't help it that one console does things better then the next when it comes to specs and performance. They want to close there ears and scream that everyone is bias even when developers themselves mention the plus and minus of owning each console. It just so happens that the x1 has allot more minuses then the PS4.

Alan_Shore1518d ago

Because ps4 was mentioned in the presentation they just didn't show the performance of the ps4. Probably becuase there roughly the same as the article state's

Tatsuya 1518d ago

LOL so many butthurt Xbots I see, tell me, what did you actually expect from a weaker box they called a console?

I bet you are one of the funny ones who would believe anything MisterX says. Stop trying to believe that the Xbone can be more powerful than the PS4. Here's the truth for ya, that can never happen !bam! Since, PS4 is the most powerful console on earth right now!


Alan_Shore1518d ago

You sound like you would be a derrick in real life ;)

candy_mafia1518d ago (Edited 1518d ago )

Dang!, so much misunderstanding on something so simples....or, so much hard feelings that PS4 must not be mentioned beside it's lesser counterpart maybe?.

Can people really get this salty?

It must really hurt those that take our hobby too seriously, that PS4 is being shown to be far more capable than the competition.

Can't go on forever hating on PS4 owners who had nothing to do with the architecture of their console, that turns up crapping on it's nearest competitor.

One has the power of the cloud the other has the power of the fog?

ILive1518d ago

Lmaooo! Im guessing im the only one who finds your comment funny.

Dasteru1518d ago (Edited 1518d ago )

-Power of the cloud (singular) Only has access to one cloud, clouds are far away so high latency.

-Power of the fog. Fog is a grouping of clouds so more power, and it is close to the ground and therfore more accessable.

CrazedFiend1518d ago

Actually, it's not really the cloud. In Cali we call it the "marine layer" and when the sun comes out, it just all bakes away.

AndrewLB1517d ago

Yeah. It's just wet enough to completely f**k up your clean car you spent two hours detailing the day before. Or make the 605 freeway just slick enough to cause a big-rig to dump 20,000 gallons of honey all over the freeway yesterday. I got stuck (excuse the pun) in traffic for two hours cuz of that mess.

windblowsagain1518d ago

Fog is much better.

It blinds your enemies.

Edvin19841518d ago

This is kinda interesting to see, as we really have no clue or me at least to what programing language the systems are tied to. I think something like that would limit the porting greatly, and before someone says the program to metal yeah with a compiler/assembly of some sort not machine code thats for sure as that would be crazy.

I wonder what the X1 is probably something along the line of C#. DirectD directive of some sort. Also, any one have a clue what the PS4 is using?

n4gamingm1518d ago

Thats pretty efficient for the Xbox one. 🙏

dantesparda1517d ago

Then its also pretty efficient for the PS4.

n4gamingm1517d ago

Yes but i'm only concerned about the Xbox at the moment don't have a ps4 yet
