i tried it with AA off, but it decreases my fps drastically.and it also looks terrible.

Nope, but this is partly 1Cs problem.

Too buggy with Vsync+triple buffering and other problems, the 11.7 is better

I found crossfire performance even without radeon pro to be better and smoother with 11.8 than any other driver ive tried. Radeon pro just gets quite a few more avg a max FPS out of it.

I was playing online last night and was getting avg 150FPS and max 300FPS on Repka 3 and super smooth with everything maxed except using high textures and 8xAA, SSAO on, Vsync off. 11.8 Best driver yet! (with radeon pro lost planet dx10 profile)

Why do you have 8xAA? Does anti-aliasing actually work for you?

Yes it does work but only on certain things.

11.8 are working best for me as well.
