Bug description:
This is a performance regression specific to the unityshell plugin.
While enabled, graphics are slightly choppy and do not perform as well
as Gnome Shell etc. Simply disabling the unityshell plugin seems to
solve the problem and graphics are smooth again.
ORIGINAL DESCRIPTION:
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System ->
About Ubuntu
Description: Ubuntu 12.04 LTS
Release: 12.04

3) What you expected to happen
3D-Apps should run much faster.
4) What happened instead
I upgraded my system from ubuntu 11.10 (was using PPA from Daniel van Vugt)
to 12.04
and then I noticed that 3D-Apps are running slow with unity.
I have noticed this with ioquake3, xbmc, blocks that matter, revenge of the
titans…
I compared the performance of ioquake as an example:
1260 frames 21.1 seconds 59.6 fps 8.0/16.8/34.0/3.0 ms compiz gnome classic
(2 gnome panels)
1260 frames 34.4 seconds 36.6 fps 6.0/27.3/52.0/7.8 ms unity
The target FPS should be 60 FPS (Monitor has 60Hz).
I also have attached some information about my system (gfx_info.log).
