Well if its the drivers causing problems..I'm left scratching my head at the moment...
I installed the demo without Catalyst control center installed (crashed all the time with version 7.3 during boot up) Game loaded fine, seemed a little on the slow side with Crossfire X1950 Pro video cards. Thought that it was a video driver issue.
Got home later that day, installed lastest Catalyst 7.4 Drivers, my CCC crashes stopped. tried ToW again...slide show..1-5 FPS.
Uninstalled 7.4 drivers just now, installed 7.1 drivers per recommendations here and now the Program crashes every time I try to launch it!
I'm re downloading it at the moment, will try a new install to see if it fixes it.
