I recently purchased a computer with an Intel Core 2 Duo E6600 processor, 2gb of DDR2 800 ram, and a Nvidia 8800GTX video card. I am playing BF2 and Oblivion and I'm getting strange artifacts. The artifacts only occur in shadows (only on objects and NPCs). The shadows flicker constantly and really get on my nerves. I installed the drivers from the disk that came with the video card and I have the latest version of DirectX. I have Windows XP Professional x64. I really need help getting things normal and flicker free. One other thing: When I start Oblivion and go to options,(not in-game), I try to set HDR and 8x AA at the same time and it won't work! I thought this card can do that! Also some of my games get errors telling me it can't recognize my card and something about OpenGL. ANY help would be greatly appreciated. Thanks!
