playing campaign last night, I was at pavlovs house and everytime I ran into zabs house, things got really weird! I could see through most walls and floors. the sky was black. I haven't changed drivers or anything lately and really never had the problem before and I doubt I could recreate it if I wanted to. anyone else have this kind of problem playing in campaign mode? I haven't cleaned my gpu in the last couple months and it's been running a lot. but I don't really think that it. I guess i'll leave it dusty for now and see if this happens again. if it does, i'll yank the card mid-game and blow it clean and see.
