** Description changed:

- I'm running ubuntu 12.10 with a Geforce Gtx680 + 2600k + 8gb, and compiz
- performance is awful in the desktop and playing games.
+ Using the NVIDIA driver, moving or resizing windows freezes and stutters
+ (especially if some other window is redrawing).
+ 
+ TEST CASE:
+ 1. Open a regular window (Nautilus or Terminal)
+ 2. Verify you can move or resize it with ease.
+ 3. Open another window that will render graphics constantly, like glxgears.
+ Expected: Still able to move and resize the first window with ease.
+ Observed: Display freezes and rarely updates. Have to stop glxgears to move/resize windows.
+ 
+ ORIGINAL DESCRIPTION:
+ I'm running ubuntu 12.10 with a Geforce Gtx680 + 2600k + 8gb, and compiz performance is awful in the desktop and playing games.
  
  Dragging a window across the desktop is a pain, because it stutters so
  much it's not even funny. Compiz 0.9.7.8 doesn't have this behavior, so
  something got broken in this release.
  
  Now, about opengl games. It's also a terrible experience, and no matter
  what settings I try there's always a lag feel. Games simply don't run
  smooth, despite the frame rate that shows on screen. This behavior is
  present in both 0.9.8 and 0.9.7.8.
  
  By running ubuntu without any effects (gnome classic panel) games run
  super smooth without any lag or stutter.
  
  By the way, I'm running 304.22 driver with default settings, but all
  previous drivers show the same behavior.
