trouble with ATI Radeon AIW 9200
 

I've been reading through a lot of posts about this card but none seem to help me with my problem. FIrst off I'm running the fglrx driver with my card as it seems to be the correct driver. The problem I'm having is when I play games and use the screensaver it is extremely sluggish. I ran glxgears and everything seems normal (I think anyways) but I was wondering if theres any way to determine whats causing my bad perfermance. Any help will be appreciated.
