Is something wrong?

post #1 of 7
Thread Starter 
Ok, so I can barely run Physx with Mafia 2 on my SLi 285 overclocked setup. AA is at 4x, and I even turned off SLi, set my 2nd 285 dedicated to Physx. When I run the Physx benchmark, it starts out with rapidly changing FPS, and then stoops lower and lower, flattens out at 20 FPS.

My i7 is currently at 3.8Ghz, anyone know what the problem is?

In BC2 I get between 60-90 FPS, if that helps.

Thanks for helping.

If you turn off SLI then you only have one card running the game, which I am pretty sure is a bottleneck. You need a dedicated Physx card in addition to a strong GPU to be able to crank up all the IQs and Physx

I have two cards, two GTX 285s. I set one dedicated to Physx and the other for game rendering, your post makes no sense to me. They are both strong GPU's, that's the problem...

Perhaps one of the cards is failing. Is there any overclock on the cards?

Factory overclocked. It's been this way for many months now.

Please allow time for us to reply since we don't do this as a paid job GTX285's are strong cards, but even my 470's in tri-sli have a hard time running everything at max settings with physx enabled, its just a tough game. Try overclocking your video cards further with afterburner, there is probably quite a bit that they can go, even a 10 - 15% overclock would help playability in your case.

Again, tough game, hard on any video cards and it brings even the newest stuff to its knees, AA is very tough on graphics cards as well, no real fault of your graphics cards
