I have a ATI Mobility Radeon 4200 HD and well, lets just say my game crashed after 15 minutes of running. I did , however, find a fix and it is working SPLENDID. If you are using any ATI Radeon and are having issues with performance, Uninstall the 12.4 and the 12.4a hotfix driver and re-install 12.3 driver(Google it). I was absolutely stunned by the turn around. The game is actually playable and enjoyable now. I hope this helps some people that are frustrated as I was last night..

Happy Hunting.
