Oh, what I meant was , in the previous instalation, which was Windows 7 RC1 7100, I was running the game with the video card in plus the drivers
that came with it. I still had shabby performance though it was way better than the last system I ran but, the game performance is the same now as it was before I installed Windows 7 Home. I now have a Quad Core 2 Intel. As of now I have not yet installed the graphics drivers for my GTX 285 and I am able to play ArmA2 with no problems, well, some slight performance drags though. From what I have heard, my system should run the game with awesome FPS performance.
So no, I have not installed any drivers yet from the CD or downloads, for my graphics card. But strangly I can run games.
