I got similar problems using single monitor configuration, just after upgraded
my ATI card driver to the latest AMD propietary driver (12.2). Compiz used
50-80% of my CPU.
Before I used AMD propietary driver (12.1) without experiencing this problem.
So I consider this as a regression.

I have had this issue for 1-1.5 year despite of my and other bug reports. It
was a pain to use Unity with compiz or compiz alone. Had to use 2d or nouveau
drivers. Nouveau got new issues in 11.10 so it become even harder.
Certainly some bug exists in the proprietary drives. NVIDIA doesn't care
@tseliot, please escalate this issue with NVIDIA.

Unity/compiz has sluggish performance on dual-head with nvidia driver
To manage
after a few days - my compiz takes 72% cpu (of 400 , quadcore)
- killing it makes windows move smmoth and fast again (wobbly windows)
- then it's back to 214MB and slow within a few days..
Is this the same bug that this thread is about ?

conclusion seems to be:
1) The problem is apparent on both ATI and Nvidia hardware.
2) It only occurs on multiscreen setups

The process that is consuming 50 % of the cpu time is nautilus on my system.
Deactivating nautilus for example by switching to XFCE solves the problem,
though it's not a good/real solution.

Just to chip in, this doesn't appear to be confined to the 8xxx series
nvidia cards. I've seen this on G96 (Quadro FX 580), GT216 (Geforce GT
220) and on GF108 (GeForce GT 430). Not high-end cards by any stretch of
the imagination, but all should be more than up to the task.
