I figured out why. It's because of the Xrender based compositor Metacity uses.
It is limited to 50 fps at the moment, I have tried to increase the refresh rate, but so far I haven't noticed a difference.
It seems to work fine if the compositor is turned off, so I guess this problem lies with metacity?
