Hey everyone,  
Those of you with ATI cards - rejoice! A new version of the Catalyst driver is out. Version 4.5 to be precise 🙂

I had to uninstall them, they slowed Y’z dock down from 75 fps to less than 5 fps ☹

Did you uninstall your earlier versions of the Cat drivers before installing the latest version? I had the problem also. I had 4.3 installed, and I installed 4.5 over it. Simple things such as right click menus lagged before appearing. Uninstalling and THEN installing fixed the issue for me.

It may work for you also. Doing a vodoo dance during installation does not hurt either 😛

Cheers!

I haven’t had too much of a chance to game, but I tested it out in WarCraft III, and it seemed to work well. I have not benchmarked it using 3DMark2001, so I am not sure what the before and after performance increases or decreases may be 🙂
