While playing Starcraft 2, there's a cutscene (rendered) that has always choked at one graphics-intensive part. I have an overclocked 6950 2GB; on paper, it shouldn't be a problem for the card/system.

Two recent things led to seamless performance in this particular cutscene -- closing the program "Actual Window Manager" (which I suspect hooks the GPU/Windows desktop management in some way), and setting the compatibility to "Disable desktop composition".

Could this just be a placebo or random luck? Or does desktop composition take away from the GPU's performance?

And additionally, would I get even better performance if I also disable "Visual Themes" (theoretically)? I don't know what the difference between them is.

(Of course, I can and will test them out in practice, but it'll be difficult to judge if disabling visual themes will give minutely better performance).

I would run a benchmark to test (FutureMark comes to mind) –  soandos Jul 6 '12 at 22:25

If you are playing fullscreen, then all background graphics processing should be disabled and you shouldnt have a loss of performance. Do you have a second monitor attached? If so, then the GPU would have some resources dedicated to that.
