Just now, im at a friend, i installed the game and we keep getting these weird colors on buildings, i think his graphic card is the problem(Nvidia Gforce 6200 LE---512 mb), gorge was the most damaged map.
Looks like a texture problem, as though it's not properly rendering those particular textures.
Can someone hop into the game and check to see if all those are the same texture? If so, it's likely something about that texture is the issue -- either it's missing (in which case, re-downloading the Live folder may be your best solution), or it's in an odd format the video card is having trouble rendering (in which case, I'd love to know what format that is).
