Right, some more testing.
I turned off crossfire in ccc and turned off AA in the game and applied it in ccc together
with quality on all settings and vsync on (but no triple buffer) plus cat AI to lowest slider
position ( I know its not off ) and the result was smooth, stutter free and no flashing texture.
I have also upgraded to cat 11.4 and lates CAP, 11.3 cap5 (no importance since crossfire is
siabled).
So untill crossfire is fixed it works again
