Did you try disabling v-sync? also, disabling the "detect refresh rate" (or update rate, i have it in spanish) and then move the refresh rate bar to the right (will mark 200).
It resolved (almost) all my problems with compiz in my system (but i'm using intel). I use to do the same changes for nvidia.
