Comment 120 for bug 861061

I'm sure there are other performance bugs we haven't pinpointed yet. If you have Sync To VBlank enabled (which is default) then 60 FPS is probably to be expected. Because the framerate should be the same as your monitor; never higher.

Unfortunately with a few compiz/unity performance bugs pending and their fixes not available for testing yet, it's hard to tell what's what. And very difficult for anyone to identify which bug they're experiencing with certainty. It will get easier as more fixes are released...
