Found a fix for Raedon X300's

Great find!

What problems did you have before changing this setting and where in the control panel is this setting?

To get more fps, turn off shadows, ssao, bloom (all post effects in the game options really), refractions, world reflections and set texture quality to medium. Also turn off any application in the background such as virus programs. That should gain you few fps!

And if not, your card might be too weak :/
