By the way, if anyone is playing this game and has an ATI card who already notices that the Catalyst 4.6 driver set causes flashing textures, here is two things:
1. ATI is aware of it and are working on it, they have stated so on their site.
2. If you are thinking about buying one of the new Radeon X800 cards you should know this problem affects these cards also. I have the X800 XT Platinum Edition and the driver disc comes with 4.6 on it supposedly.
