Okay, so I go to play episode 1, and I notice the trees and the bushes/tall grass are flickering. I can also see a sort of box shape around the stuff. I haven't played the games with this particular video card before, so it might be that. Anyone have this problem with AMD cards? I'm using a Radeon HD 6770, any help would be greatly appreciated.
Episode 2 is working for you? Are you using Steam?
