In order to avoid this bug becoming a vague never-ending discussion about hearsay desktop performance, I have updated the bug title and description to be more specific and reproducible. Now the bug is confirmed.
If you can't reproduce the bug using the exact test case in the Bug Description then please don't add any more comments to this one and log a new bug instead. ** Summary changed: - compiz 3d performance regression + Running compiz makes 3D apps like glxspheres (VirtualGL) perform worse. ** Description changed: + TEST CASE: + + 1. Install VirtualGL from http://sourceforge.net/projects/virtualgl/files/VirtualGL/2.2.90%20%282.3beta1%29/ + 2. Run /opt/VirtualGL/bin/glxspheres{64} + 3. Note the frame rate that glxspheres reports. + + This frame rate is significantly lower when running compiz (Unity), than + when running Unity-2D or Gnome Shell (3.2). + + ORIGINAL DESCRIPTION: + A recent update to compiz in oneiric has had a big impact on 3d performance. The desktop feels more sluggish, and the glxspheres benchmark indicates about half the performance compared to metacity and mutter (on my Sandy Bridge GPU I get 30-32 fps in unity/compiz vs 59-60 fps in both unity-2d/metacity and gnome-shell/mutter). Previously compiz matched the performance of metacity and mutter. I also tested the oneiric beta2 live CD (amd64) and performance was similar (ie regressed compared to beta1).
