I use an nvidia geforce 8800 GTS 640 meg video card, it's currently one of the top end video cards on the market. I load this game KotoR II and its telling me I don't meet the recommended video requirements for the game and when I try to load it on max settings all the textures are pupre white. I don't know what the problem could be....I can play any other game I have on max settings! IS there an issue with this video card and this game?
