Problem: While playing a game with high fps (>30), which should be smooth, the game stutters. For example, when I play Minecraft, which usually runs with 40-80fps (you can see the frames per second in the game), the game stutters. 50fps look more like this game in the video http://www.youtube.com/watch?v=5-UpHp_p_8I So 50fps correspond to 15-20fps, with lower fps, such as 30fps, the game runs like with 10fps.
I only see the stuttering with my Nvidia (GT 540m), with my AMD GPU (6850HD) all games run fine, even low fps games (<30) are smooth. I also don't see the problem with other window managers (Mutter and Metacity), the games run fine with Nvidia there.
Refresh rate of Compiz is set to 60fps, VSync is activated and "Force full screen redraw (buffer swap) on repaint" is checked.
I can't remember having this issue with Ubuntu 11.10, so this problem probably came with the newer versions of Compiz. The version of the GPU driver is 302.17, but I had the stuttering with 290.10 and 295.xx too. |
