Gaming/Graphics Performance On Unity, GNOME, KDE, Xfce
Phoronix: Gaming/Graphics Performance On Unity, GNOME, KDE, Xfce
It is going on a year since showing how Unity, Compiz, GNOME Shell & KWin affect graphics/gaming performance, so here is an updated 2012 look. In this article are a variety of OpenGL benchmarks run under the current latest desktops as will be found in Ubuntu 12.04 LTS: Unity, Unity 2D, GNOME Shell, GNOME Classic, KDE Plasma, and Xfce. AMD and NVIDIA graphics were tested with both the latest closed and open-source drivers.
How can performance under catalyst be so uniform?
There must be some external reason that the performance under catalyst is that uniform across so many tests and so many different desktops. I think it must be that the limitation is some vsync setting, or some other limit other than the performance of those desktops. Remove that limit, and I think the results will change a lot.
