Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
5589 frames in 5.0 seconds = 1117.730 FPS
5369 frames in 5.0 seconds = 1073.715 FPS
5699 frames in 5.0 seconds = 1139.670 FPS
Obviously, it doesn't sync to the framerate with PRIME.
On the other hand, nothing is displayed in the glxgears window.
I have llvm 3.4-4 and Mesa 10.1-rc1 from Fedora 21 rawhide.
Make sure you are running a compositor.
Turning on compositing in MATE fixed it. Thank you very much.
It seems I will have to keep Rawhide on this notebook. :-)
Best regards,
