just wanted to throw a heads up to everyone..
if you are running an ati card and are having problems with your system locking up, or your screen becomes an unviewable mess, try the following (it worked for me)
>goto Run
>type msconfig
>Services tab
>uncheck:
Ati HotKey Poller
ATI Smart
>click ok, and restart.
This worked for me, and I know many people have been having this problem with certain maps in the game.
