Yep, did that.
I'll try runnin Unreal 3 again maybe, as previously I've had no issues with that. see if there is a paralell, maybe I've fiddled a little too much with settings on the video card.
So far this is even happening on the main menu, I can see both the asteroids and Cybertron through them. I have only played the first 2 minutes of the decepticon campaign as it's just impossible to figure out which way I'm supposed to be going.
