Comment 129 for bug 803943

I can not confirm that disabling vsync would help. with and without vsync compiz consumes 20%-25% cpu when i move a small window around.

btw, dimitri, vsync is an essential technique in computer graphics to prevent tearing ( http://en.wikipedia.org/wiki/Screen_tearing ) but it never really worked for X11. Ubuntu 12.04 is the first release that really reduces tearing but now we have this cpu issue. :(
