Compiz using 8% - 25% CPU continually

Question

Any tips?

Intel Core 2 Quad x64
Ubuntu precise 12.04
Dell OptiPlex 760
nvidia graphics driver

Same problem here... Dell Precision, dual core, NVidia graphics card. — Matthieu, May 17 '12 at 18:37
@JosuhaRountree I know what you mean. I think you should give Ubuntu another chance. Just don't use anything above `11.04`. Get `9.10` or something and if you want to use `11.04` or `11.10` make sure that you get `gnome-panel` which is the closest thing to gnome 2 and significantly reduces the grief of compiz. I use Ubuntu `11.10` with `gnome-panel`. I am a mathematical programmer and with this config I end up using only 500MB which is 1/16th of my RAM. — dearN, Oct 28 '12 at 13:57

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.

Any idea why this works? – Alex Jun 24 '14 at 07:18
Also [documented here](http://followthegeeks.com/compiz-is-consuming-too-much-cpu-heres-the-solution/) which additionally suggests to change the "Texture Filter" from "Good" to "Fast". – Torben Gundtofte-Bruun Jun 23 '15 at 06:19
Worked for me too! – Amorphous Aug 19 '15 at 15:04

After the vsync setting I turn off window shadow where I can, and some same decorations. After that compiz use 1.4-3% – sarki_roka Apr 09 '20 at 08:53
This worked but then I noticed high compiz cpu use when watching videos on google chrome. Watching in full screen fixes the issue. – mchid Apr 05 '21 at 03:22

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.

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.

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.
