I can play a SP map and it runs perfect. But if i play the campaign it stutters so bad quite often it is sometimes unplayable. It actually is more like freezing. While stuttering is like a bunch of quick freezes and releases, this actually freezes the screen for up to a 3 or 4 seconds and occasionally freezes completely and i have to hit the restart button. I have reintalled the game and added all the patches i could find to no avail.
So i think i need to do a clean uninstall. If anyone can tell me how i could do that and which patches are necassary and which might be problematic maybe that will help. Or if anyone knows what it is that causes this, that would be even better. Thanks.
