Yes, please tell us. I have dual nVidia 280's running in SLI mode. I have downloaded the latest drivers. I have onboard Realtek sound that I downloaded the latest drivers for and it did nothing. I disabled the onboard sound and installed an Audigy 2 ZS sound card I had and downloaded the latest drivers but the screen I get on bootup is the normal bootup but it won't allow me to make any inputs...it just freezes.
I tried running the game in Windows XP compatibility mode...same problem. I have admin privileges but that hasn't helped.
I have NOT tried downloading DirectX9c as some have suggested. I will and report back. I must not be the only one in America trying to run Crysis on Windows 7, 64 bit.
