Mirrors edge insane FPS problem

[Anj]

Ive googled pretty much everything related to the problem and nothing works, heres my setup:

NVIDIA Surround using cards : 2X GTX 580 Phantom Gainward 3GB Running on SLI
2 Monitors hooked to first card
1 hooked to second

To enable surround, of-course, both cards need to be working together so SLI is auto-enabled upon setting up surround (no sli specific settings available in game profiles under 3D settings.)

The only option I can find is "CUDA - GPUS" which allow you to select 1 or 2, not sure what this is but it doesnt help.

Ive noticed through researching that mirrors edge has issues with SLI.
The game FPS laggs insanely no matter what graphic setting at 5760x1080
The game is completly smooth, highest FPS, highest/lowest setting at 1980x1080
Both on SLI

Apparently only enabling one card and disabling the other to stop the game from using both cards works but that option isn't available nor would it work because for surround both cards need to be enabled, right?

I use the FOV fix with 5760x1080 res
I have enabled or disabled PHYSX and even removed the files from the games directory but nothing changes.

Ive tried altering 3D profile settings but nothing changes, the game just wants to FPS lagg (camera movement, 5FPS) the same exact way even if put it up to forced 32AA.

Skyrim can run at ultra maximum settings on 5760x1080 RES with over 60FPS so I'm positive its not a hard-ware issue, then again, sli..

Any workaround?

Fixed using nvidia inspector and setting SLI mode to single
for google searches^

lock please

I ever used SLI with the game, but I do recall some crazy framerate problems with certain AA + vsync settings. Though i cannot recall which combo killed frames..

I remember any kind of AA destroyed this game for some reason, turning it off, gave like 5x framerate.

Note sure if that is still the case but worth trying.

Yep, thats it, btw you could have checked first our game's Detailed Report here at WSGF - http://widescreengamingforum.com/dr/mirrors-edge , under "Eyefinity / Surround Specific Solution".

Setting to single card allows me to set AA to 16 and recieve 50+ fps

16AAQ however brings back the problem
