** Description changed:

  When compiz is enabled, all of my games have a slight jag to them,
  skipping a few frames every second. This choppiness can range from
  merely annoying to headache-inducing, depending on the game. This is not
  Unity-specific as running a unity-less compiz session still presents the
- issue. Furthermore, this is not an Nvidia binary issue as the nouveau
- driver makes no difference. Disabling vsync or manually setting my
- refresh rate makes the issue worse. Also, desktop animations appear to
- be smooth with no problems (though they may just be too short to really
- notice). I have noticed that smooth scrolling with firefox also drops a
- few frames: not enough to notice the issue when using compiz but I
- noticed it when I found smooth scrolling to be butter smooth under
- unity2D.
+ issue. Furthermore, this is not an Nvidia binary issue as the

  Game performance is butter-smooth when I use Ubuntu 2D. Not a hiccup to
  be had.
  
  For an example of the choppiness, please see the video. Watch the
  clouds. Since the video was recorded at only 15 fps, the choppiness is
  slightly higher than what I actually experience.
