I just installed a GeForece 5600XT, and it seems to work fine until I start a game. FS2004 and il2 Sturmovik show HEAVY screen corruption, skies are red, textures blend into eachother and ebentually the screen is just full of colors, then my plane crashes (cause I cant see it!) Any ideas? I cant figure out any adjustments that I havent already made. I had no problems with my MX440 card, other than non direct X9 compliancy and much more stutter.
