OK, if I disable unity-plugin via ccsm it still runs slow so it looks
like I should log it against compiz. The unity animations are still
fast, btw.

fwiw I just upgraded to Precise, and glxspheres (just running through
the intel card) now only gives me 1-2 frames per second. Is this a known
issue? Sync-to-vblank makes no difference. I'm running compiz

If you can reproduce the slowness while you have the Unity plugin
disabled in ccsm (unity not running) then log it against compiz-core.
If the slowness goes away while unity is disabled, then log it against

If in doubt, log it against both.

I'm sure there are other performance bugs we haven't pinpointed yet. If
you have Sync To VBlank enabled (which is default) then 60 FPS is
probably to be expected. Because the framerate should be the same as
your monitor; never higher.
Unfortunately with a few compiz/unity performance bugs pending
Yes, that's true if I run glxspheres through the intel card, but running
through optirun, the nvidia card doesn't respect the sync-to-vblank
setting, so the expected result is a rate considerably higher than the
60 fps monitor. I get 150fps normally with the fixed unity/compiz, but
it regressed

So far 4.28.0 is working nicely on my system, although after switching

Yes, my fix or any fix for this bug should reduce GPU power consumption.
It may be very significant with some drivers/hardware, but is hard to
prove without careful testing. Especially since GPU power hogs don't
usually show up in CPU lists like top.

I've just installed all the packages from your PPAs (both Unity and
Compiz) and I find that whilst the performance is slightly better than
it was before, it's still not as good as it was in Natty (or in the
Oneiric default version of Compiz with Unity plugin disabled). I'm using
a ATI Radeon X1250
@EliCoten: Regarding when you are using the unity plugin, how recently

Great, trying them now on my Sandy Bridge setup.
My first observations are that right after logging in I now get 130-150
fps instead of 100-120 fps from the nvidia card running through
virtualgl, and that I'm not seeing tearing any more when I move windows
around. Thanks!

Thanks! Just installed them both on my laptop with an Nvidia NVS 140M
and a C2D T9300. First impressions:
- I can also confirm the increase of the number of fps in glxspheres to ~140
just after logging in. This is identical to the results in gnome-shell.
- No tearing when moving windows around
Experimental fixes for this and related performance bugs are now available
for testing in ppa:vanvugt/compiz and ppa:vanvugt/unity. For the best
results I recommend trying both together. But testing them individually is
useful too.
IMPORTANT NOTES:
* The fixes in ppa:vanvugt/compiz REQUIRE
Clarified the bug title because this bug actually affects all apps, not
just 3D. It's just that most people don't or can't measure the frame
rate of 2D apps. :)
