** 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). 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. https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/996343/+attachment/3136325/+files/bug.ogv - While this game and many others (including almost all windows games - played through wine) are this choppy, there are a certain very few games - which retain butter-smooth play. They are rare, however.
