I guess this topic has already many flavours (i.e. xorg, opengl), however I'm interested in the performance people are getting when running glxgears (with no arguments).
On archlinux one needs mesa-demos package, on debian.. dunno
On my archlinux it is around 27.2 FPS...
What are the other results? I guess the huge benefit will be once someone manages to get the right drivers/access to the GPU but from my understanding this is not currently possible and all the results should be around 27 FPS.
