Be sure DRI is working. use glxinfo if you need to verify if it's active.
If you don't have DRI working, then most of the graphics will be done
on CPU. Or at least that's how my laptop did it.

Hmm, I also have an nvidia GPU, and my system doesn't exhibit this
behavior. Of course, I get the black-windows bug due to a memory leak
in the drivers, but certainly no excessive CPU usage for any of the
beryl effects.
