I have the same problem with the VGA compatible controller: nVidia Corporation G98 [Quadro NVS 450] (rev a1) and dual twinview monitors. Unity compiz was slow in 11.04 but is almost unusable in 11.10. I don't think it's a problem with the physical graphics card because Windows Aero stuff runs fine.
