This is likely due to the extra strain compositing places on a system. However there are also likely inefficiencies somewhere in compiz or in the graphics drivers as low fps is a problem even on powerful systems playing basic 3d games.
One possible solution is to disable compositing when a 3d game is launched, but as of yet I am unaware of a way to do so seamlessly
