How do you modify inf file btw? Is it important to do this?

Yes. If you do not add the hardware information to the Nvidia.inf file, the driver will not install. Here's a link to Guru3D with a link to the driver and the modified nvidia.inf file.

Essentially after you extract the driver normally, you replace the nv_disp.inf file. Which is usually located at C:\NVIDIA\DisplayDriver\275.65\WinVista_Win7_64\In ternational\Display.Driver. Just copy and paste. If you have any questions just ask there. A lot of helpful folks. BTW a correction to the above. AFR 2 was giving some flickering in the water textures. AFR 1 still gave decent SLI scaling without the flickering.
Nvidia needs to come out with a proper SLI profile. Hopefully the 280.xx coming out next week or so.

Are your SLI framerates good in fullscreen or are they windowed like Grathos?

Also, is your setup just the new driver + .inf file + AFR 1? Or are you doing, as Grathos said, this: SLI compatibility bits (DX10): 0x000000F5?

Thanks for finding the driver stuff. I'm hoping it helps with my GTX 470s.

Man, I'm still very hesitant to buy this game. I've got 3x 3GB GTX580's in Tri-SLi and 3x displays @ 5960x1200. I don't want to have to drop back to using two cards (through drivers or by removing my third card) just to experience this game. Even then, I'm still not sure that the Aspect Ratio will be sufficient to take care of the stretching that the original IL-2 had.

Oh man, you should be banned for posting things like that...

Unlike IL2FB the 3Renders option is not working (yet) in CoD so it is a problem.
The only solution I found was to run the game in Window mode as my pictures show.
So, the 3Renders option is the key and we have to wait for this to happen before we can enjoy nice wide view.


In the meantime, the power of one 580GTX 3Gb will be enough to enjoy the game in full graphics so if I were you, I would not hesitate a moment buying the game and enjoying the graphics detail on single GPU mode. Afterwards with some searching, you will be able to activate the second GPU as well and this will be more than enough.

By the time the 3Renders option will be available I am sure that SLI ill be working without any shortcuts and this will be the time where three GPUs will show their value.

nice rig, by the way!!!

I'm running full screen 1920x1080 all in game settings maxed I'm averaging 55-60 FPS in most areas with 80-905 utilization on both GPU's. Where I drop into the 20's is in urban area with a lot of buildings. My current setup is the new driver using the inf file (it's required) and AFR 1. I am not using the SLI compat bits. All the modified inf file does is add hardware information for other Nvidia cards so the driver will install. Reinstalling a standard GeForce driver will not be affected.
