I have the lastest drivers installed.
When playing in windows XP on multiplayer it runs fine but if in single or campain mode after a while it flickers white and you can't see anything untill you look at the ground then goes back to normal.
Also i have installed it on Windows 7 And it works perfectly no problems at all, looks like i will be upgrading to windows 7
