I've just put the latest Cat driver and control Center on, and I'm not impressed with it either, for two reasons.
First it seems to be far more choppy even with all the whistles and bells turned off, second, when I download it from ATI, and installed it, it also installed the dreaded Steam without my say so (which I subsequently immediately removed). I found that so annoying that I decided I'm not going to get another ATI card when I upgrade (which I'll be doing shortly).
