I see you've already tried the framelimiting options which can also be the cause of the problems you're having.Įdit: already tried this I see Good idea ! But I just tried and it doesn't work If this doesn't help, you could also try enabling Vsync.

These are all GPU related improvement - if I'm not mistaken & increase the load on your GPU. Furthermore, enable pixel lighting and maybe even MSAA. Try increasing IR (rendering resolution) to 3x or 4x. When I increased the load on the GPU, the clock-speeds didn't go into low-power mode and the stuttering was gone. Then it could switch back to 'gaming' speeds when a scene got a little heavier on the GPU - this switching back & forth caused choppiness for me in games like Donkey Kong Country Return, Star Fox Assault and Soul Calibur 2. What I discovered, is that when your GPU load is too low your AMD GPU can clock back to low-power clock-speeds.
