 I also reported on irc Valley stutter on Kabini, but now i am somhow against
reverting because performance suffer with reverting in other games.

 One other reason simply because i tested it first time on Windows today and
there i have stutter even worse then then any case we have here :D. And i did't
know that :D DX11/DX9/OpenGL any mode all stutter a lot. Our worst combination
is a lot smoother than with Catalyst on Windows :).

 So question is, is there other stuter examples than Unigine Valley?
