I've done all of this, deleted the wtf and other folders to get wow to default settings...

The result? 24fps in Dalaran with all settings MIN and 1024x768 res.

Believe me I've tried everything, the problem is with the GPU never pushing itself over 20% utilization.

Basically the GPU is a slacker, when giving all its got is 20% its capacity lol. But its only in WoW... all other games run superb!
