[quote]thanks for the tip, might re-download the game on steam and give it a shot.

K i found a way to run ME all maxed, including PhysX and AA 4x, at 5040x1050 (around 60 FPS) with my 3-way SLI rig, by forcing wtih Nvidia Inspector, in Mirror's Edge profile, SLI rendering mode to SLI_GPU_COUNT_ONE.











OMG Thx this totally fixed the problem! But now the PhysX causes the game to slow down to a crawl when they shoot the glass ...

I would not suggest buying the game on Steam to play in a surround aspect ratio. I have found that the hack does not work with the Steam executable. But if you own the game, I guess it would not be morally wrong to download a backup copy through other sources. As long as you own the game that is.

I'm pretty ticked at EA for cancelling work on Mirror's Edge 2. DICE probably could crank out a really nice sequel with their new frostbite tech.

Thanks, mmm no here its all fine, rock stable FPS around 55-60, have you updated game to version 1.01 (the patch includes some physX fixes) ?

Just updated the game, but it didn't fix the problem, when PhysX is on, the framerate is unplayible.
PhsX is a big disappointment, I got nVidia card because of PhysX and this is one of the handful of titles that actually is supposed to support this feature, but it makes the game unplayible. I tried setting PhysX to GPU 1/2 or both, but the problem persists no matter what.

How does nVidia get away with this type of false advertisement?

Maybe it only works for you because tri sli allows you to dedicate an extra card solely to PhysX?
(Sorry, I just don't think PhysX is worth $350 extra investment at this point, the total number of games that include it is probably less than 10 they advertise on their box all of their cards are supposed to have PhysX support to justify paying permium over ATI)

No, i havent dedicated a card for PhysX, its 3-way SLI and physX is set for "Auto-select (recommended)".
Check the GPU usage of the 3-way SLI, its 85%+.

I finished this game with a Radeon 5870 + Geforce 9600 GT (for PhysX) combo and it worked superb, however I had to do a little trick to make PhysX work properly. This game has some PhysX DLLS that must be removed to make PhysX hardware acceleration work (otherwise it will run in software, even if you enable hardware PhysX in game).

So, you must remove (or rename) PhysXCore.dll and PhysXDevice.dll from Mirror's Edge binaries folder. Try it, it will work like a charm.

Maybe it works for some rigs, i havent deleted anything and i got rock stable FPS all maxed, including all gfx options enabled in the .ini file plus AA4x.

Obviously, if it's working fine you don't need to change anything, maybe you have a game version that doesn't include those files on the binaries folder, or a version with newer DLLs. But people having performance problems should try what I posted, it has worked for a lot of people including me.
