  1. I also had compiz constantly taking around 10-12% CPU. I installed ccsm using 

    sudo apt-get install compizconfig-settings-manager

    launched CCSM and under the OpenGL unticked sync to vblank. Now compiz is only taking up 2-4% CPU.

    This website also suggests setting Texture Filter to fast.

  2. Had the same problem. Compiz constantly at around 40% (AMD CPU, ATI 58xx, 12.04). Then i followed the instructions in this answer and CPU utilization dropped below 10%. Hope it helps.

  3. For me in 12.10, removing the compiz settings on ~/.compiz and rebooting solved the problem. I just renamed the folder, it might help if you want to recover your settings after all.

  4. What seems to help with Ubuntu 12.04 x64 on a T61 with NVIDIA GPU was unticking sync to VBlank in ccsm OpenGL settings. Sync to vblank is already enabled in nvidia-settings so there's no vertical tearing or such.
