I have installed your PPA. Last night things seemed to be going fine, but this morning (post another reboot) I have compiz taking up 20 - 30% of a CPU when I am not interacting with any running programs. Disabling the Unity plugin reduces its usage to 2 - 3%.
I am running a Lenovo T410 with an NVS 3100M (256MB RAM), running driver version 290.10 and have DynaicTwinView disabled so the driver reports the correct refresh rate to other programs running in the system (this helps).
