Kepler is very strong in games that NV doesn't sponsor and is only under-performing in games that NV is actively involved in development. You can draw your own conclusions.

Well I was considering picking up a Asus Mars 760(sli) for 212USD but now and considering not, hmm, idk really wanted to stick to Nvidia BUT feeling like I shouldn't. Oh well..:|

Thats shitty if on purpose...

For that price a R9 290 can MATCH 760 SLI drawing much less power and not having to deal with multi card issues.

Oh I know, but I already returned a 290 XFX because even though it said 60+ fps in games I felt odd stutters I never experienced with my old 460 even at lower FPS so it scared me off a bit. Cheapest 290 I found was 269.99 near me though.

Decisions I guess, I was thinking of a 960 for 175USD but hell why does the thing not have 3GB VRam if the 280 does? You know its competition.....:whiste:

Forcing physx to cpu can get you ~15% more fps on kepler in the witcher 3.

So is it only an issue in these two titles? Like GTAV isn't though or other new games(Not sure what else came out since this Kepler issue). Seems like just bad optimizing maybe? Why would Nvidia purposely hurt their PR like this? Seems odd.

No. It's a general issue. If you look at TPU's overall performance results since Maxwell release. Kepler performance has dropped relative to even AMD. The 780 ti prior to now never came up slower than Hawaii in prior reviews.

The latest games is just a continuing trend, but it's getting worse with Kepler falling further and further behind.

Here we've got the 285 matching the original Titan. Titan should be a lot faster.

Why, is there GPU accelerated PhysX in Witcher 3?
Seems so.

There's some dll's in the bin>x64 folder

apex_clothingGPU_x64.dll
PhysX3Gpu_x64.dll

I thought I had a pretty conclusive test yesterday, but can't seem to reproduce it (in that magnitude) now, maybe it depends on settings too, or it was a bug. Should've done back to back testing. I thought I had found a spot where there was massive physx load on the cpu, but now it just seems to improve performance to keep physx on the cpu even though I have only a dualcore. I guess it was a memoryleak or something causing 100% cpu.

Testing in the nilfgaard garrison in white orchard gets me 10% better fps with physx on the cpu.

Here is some real benchmarks to answer your question.

It seems to me its MAINLY a witcher 3 problem.

Yeah thanks for this by the way, kinda looks that way, good to know because even so the 760 sli seems to be better on this game then the 290 anyways and this is the game I want to play most...well that and GTAV which they seem almost equal at?

How is quoting an Nvidia only comparison proving anything?

Also Happy, you forgot to add this in your post from your Babeltech link.

Over the past 6 or 7 months we see perhaps more of an emphasis given to Maxwell, and as it is the newer architecture, it has more optimizations to make.

Yes, makes sense, whats the point?

Is your native language English? I'm just asking, it would explain a lot of things for me, and I will be a little more understanding.

The bold is my emphasis. You chose the second half and I chose the first. I interpret the second half being emphasized by you as an excuse for the neglect of Kepler. As Silverforce says, in neutral games Kepler hardly tanks relative to AMD.

Kepler is falling behind Maxwell and AMD in Nvidia sponsored games, but keeping up in nuetral ones. How can that make any sense if you are claiming that its because Maxwell More optimizations available. The only sensible conclusion is a deliberate policy which is the first part of the quote. Any argument otherwise is disingenuous

By the way, Why this?

It is like there is some sort of agenda, people keep saying and insisting that nvidia is sabotaging Kepler on purpose. Someone posting a huge list of games showing that Kepler performance vs the 980 and they get railed on because they didn't include AMD results? Why is that? The only reason I see is that with AMD results, you can muddy up the water and keep the bologna going.

There are people who just don't want to analyze things, they just want to keep the same argument going, over and over. They have this conspiracy theory that needs everything jumbled together or else it falls apart. When you show them that gameworks performance hit is not way worse on Kepler, they ignore it. They just carry on, muddy up the water some more. Happy post real Kepler vs 980 results over a huge number of games, that's no good.......we need to throw in more elements to try to keep people confused.

I mean, shouldn't we actually be looking at this on a deeper level? We aren't some kiddy gamer forum. We are supposed to be the real tech heads, have deeper discussions and conversations.

So, now I am reading "nvidia sponsored games" instead of "gameworks sabotaged Kepler on purpose". So I guess there is that, it is actually movement. But it makes no sense really, but I guess it doesn't have to. Just jumble together a bunch of half truths and data then say whatever. I think there is a real intent here. its like, no matter what, this is the story.

you would think that people would want to get to the bottom of it. But anyone who does try, instead of a real interest they are met with.........

Anyway, of course nvidia must be creating these new game engines that sabotage performance on Kepler cards. It has nothing to do with the developers building games engines around the next gen consoles which are GCN. We also have to ignore the fact that even before the gm204, we started seeing some new modern games favoring GCN over Kepler. We are also supposed to accept that maxwell is the first architecture ever that nvidia couldn't optimize for, that its gains in performance are simply a result of nvidia sabotaging Kepler. But, if you post a huge list of games now vs before the 980 launched, then we doing something wrong because it doesn't have the 290x in it. Because, it makes the claim that kepler was sabotaged look better when the 290x is in the charts. So, from there, you know we have to ignore all of the huge AMD driver improvements (such as omega) and the fact that games designed specifically around GCN consoles just might favor GCN over Kepler.

You know, if we don't talk about all those things specifically.....
If we don't let those things be spoke of on an individual basis, then we absolutely can say without a doubt that nvidia is sabotaging Kepler and this ill part of their masterminded plot to sell more maxwell cards. By force.......

You know, nvidia probably wrote the omega drivers for AMD just to make Kepler look worse. the 290x performance gains over the years, they can't be anything other than an nvidia plot to obsolete Kepler. This is why it has to be brought up, this is why Happy was wrong for posting charts without the 290x. .....

Yeah, this is all pretty crazy to me. Its actually blows my mind.....

Project Cars with Rain/Weather, Kepler tanks hardcore, where a 960 is beating 780/Titan.

http://www.computerbase.de/2015-05/project-cars-guide-grafikkarte-prozessor-vergleich/2/

Also, one would have to compare those individual games and work out the % change over time to have a better understanding. But certainly overall performance summary charts, the gap was 5%, 980 > 780Ti and it has gotten wider over time. You could say Maxwell is more forward looking.

But I don't see anything to back that up in non NV sponsored titles. The 780Ti still hangs up there, often above 970 and close to 980.

I mean here's a few recent non-NV games to showcase how strong Kepler still is, always above 970:

http--www.gamegpu.ru-images-stories-Test_GPU-MMO-World_of_Warships_Beta_-test-ws_3840.jpg


So the question here is why is it in neutral games, Kepler still reigns up the top, with 780Ti beating the 970 and close to 980, but in recent NV sponsored games, its well below that?

Is NV sponsoring devs to push more "innovative features" that run better on Maxwell's uarch?

It could be that these Gameworks titles are heavy on compute performance, which Kepler sucks at.

No, they just aren't improving Kepler drivers for newer games. It makes Maxwell look more "efficient"
