Or DX11 that runs in a less than efficient way when it sees an ATI card and not an Nvidia? Like they did with AA in Batman? Just a guess. A bad one mabye though lol

Nope, because AMD GPUs cannot execute the PhysX path.

Nope, DX11 is a Microsoft API. The API passes the commands to the video card through the drivers.

So if this is true, GK104, a $299 GPU, will exceed the performance of a 7970, a $550 GPU, in some games, while it's performance in others will drop to the level of a 7870 or 7850 (Pitcairn). Again, if true, the fact that a mid-range GPU can outperform the competition's high-range GPU in some games, while matching their mid-range GPU in others is a positive not a negative.

I'm sure a lot of people would be thrilled if they could spend $299 on a GPU and get 7970 or greater performance out of it in popular games like BF3 and what not.

Actually I'd say that's more than likely what is actually happening.
As the games go through various testing stages, I could see how Nvidia's embedded in-house agents could give 'suggestions' that would make any programmer's job lot's easier as the programmers deal with various performance issues and they develop and optimize their coding.

Because running PhysX better gives you an increase of tens of FPS... rolleyes.gif

Nvidia is still at it. Wow.
Quote:
More to the point is antialiasing (AA) in Batman: Arkham Asylum. If you recall, AMD stated complaining about that game’s AA routines upon release. They directly stated that if AMD cards were detected, the game would disable AA for non-technical reasons. (Note: The original post that TechPowerUp refers to has the pertinent sections in the comments, not on the front page. It takes a little searching to find the post that also talks about several other games having similar ‘bugs’.) It goes on to state that if the card IDs were changed, the AA in the game functioned correctly on ATI hardware.

I'll probably have money when they finally get their next installment out. For competition sake, I hope they don't rely on Physx too much.

wow!! All I see is innovation beging stymied so compines can put fake numbers on the screen for epeen. Why have a better card when we can have smoke and mirrors. Geez and then the "higher end" cards are going to be 600 dollars. It would be nice if there was a non profit org. that could test independitly so there was none of this crap.

If Nvidia "helps" developers "optimize" their code, we might just end up with several games where this is the case.
