Any other with this problem?

Yeah, I had the exact same thing happening to me with my 5970 in true full screen.

I think it must be xfire issues. They simply do not have it working at all well.

I eventually just accepted it and have since changed to a GTX580 3 gig card and the game runs smooth consistently now (although I still get the stutters like everyone else).

Not really a smart solution though, buying a new high end card when the 5970 is a fine card in its own right...but that's what I did.
