Hm... I downloaded the newest Catalyst drivers, extracted and modified using Mobility Modder. But ATI Tool won't apply higher clock speeds when I adjust the slider. Moreover, when I tried to launch QW, it just bumped me back to the desktop with an error.
Yep, I'm stumped.
Are you using .24 or .26? Could you explain how you got ATI Tool to change the clock speeds?
This might sound silly (only mentioning it because I've done it myself a few times!) .... did you click the Set Clock button after adjusting the sliders? By default, ATI Tool won't automatically set the clock when adjusting the slider in case you accidentally bump it up to a billion megahertz or something
I've got an older version of ATI Tool - v0.25 Beta 14.
What was the QW error? There's also a hotfix for ATI drivers for ET:QW here although I didn't seem to need it on my setup (which is odd!).
