We happen at work to have users with very important needs of 3Dresources, so one of my colleagues conducted some performance tests with
and without a compositor (the compositor being GNOME 3).
It turns out that with a recent adapter, 3D applications are running a
small bit faster under GNOME, and that’s probably because it saves your
graphics card the pain to switch from 2D to 3D contexts.
1150 frames in 5.0 seconds = 229.772 FPS 1267 frames in 5.0 seconds = 253.212 FPS 1240 frames in 5.0 seconds = 247.875 FPS 1272 frames in 5.0 seconds = 254.374 FPS 1314 frames in 5.0 seconds = 262.673 FPS 1279 frames in 5.0 seconds = 255.684 FPS
XFCE:
glxgears 2110 frames in 5.0 seconds = 421.982 FPS 2290 frames in 5.0 seconds = 457.800 FPS 2241 frames in 5.0 seconds = 448.046 FPS 2279 frames in 5.0 seconds = 455.636 FPS 2191 frames in 5.0 seconds = 438.094 FPS 2246 frames in 5.0 seconds = 449.114 FPS 2218 frames in 5.0 seconds = 443.590 FPSPlease note xfce was installed on the same vm, that gnome / gnome-classic was on. It was therefore using much more memory, (it seems GDM + other gnome services are causing memory use, i will be testing that shortly). And here i will make a comparison. ahahahaha. That was it. Moving on.;)
