I am also having some trouble with low fps, currently with the auto-detect option I’m around 20 fps in Lion’s Arch and lowering my settings to best performance add a whopping two fps or something. Granted Lion’s Arch is probably the place with the lowest fps for me, but it is still rather low elsewhere. During the head-start period I had approximately 120 fps everywhere with the auto-detect option.
And this is my computer:
CPU: Intel Core i7
RAM: 6GB
Graphic card: AMD Radeon HD 6800
Graphics drivers: AMD Catalyst 12.8
Windows 7
