After turning off "Sync to Vblank" from Compiz settings (CompizConfig Settings Manager -> OpenGl -> Sync to Vblank), Enhanced Zoom is somewhat usable and the whole desktop seems a lot more faster. I believe "Sync to Vblank" wasn't on by default in Maverick but in Natty it's on by default.
@ Peter, could you try turning off "Sync to Vblank"?
