I just got done installing the catalyst 3.9 driver and directx 9.0b and the game runs like a charm on my ati radeon 9800pro. Thank you all for answering my questions I love this demo! it is the coolest game I have ever played. wow wow wow wow!!! I thought it looked good before when I had to put all the settings on low but now It looks 10000000 times better! this game is sweeet!
