In a couple of games -- most recently the Guild Wars 2 beta -- I'm getting some kind of weird performance issue with my AMD 6950 card.
1) If I have depth of field on I get no in-game screen but can still usually see any UI components.
2) If I turn depth of field off, I get the game screen back, but then sometimes part of the world will become unavailable to me. If I turn in X direction (that is unavailable) then the screen goes black. I can pass through the black and then on the other side I get the game world back. The same part of the world always seems to be unavailable, but since I can't see what's there I don't know if there's a common denominator to what I would be looking at.
I have 12.4 catalyst drivers (have updated, error occurs in both versions)
Have tried turning off any overclocking. Temps seem ok.
