Have you changed anything since these slowdowns started appearing? Version change or anything?

It may also help to turn off the pixel shaders (set to 0)
Try setting max FPS to 60 while you're there (actually, FPS of 60 shouldn't cause slowdown, its just over the maximum that the human eye can see).
Also, try closing down all background apps (start -> run -> msconfig -> startup -> disable all -> ok and reboot). Should up the framerate slightly.
