--- Comment #9 from Sergey Kondakov virtuousfox@gmail.com --- Ah, and I don't know if its normal or not and pertaining to that issue or not (maybe that confuses something else in the driver). But I can't seem to get vsync working. Earlier I used "EXAVsync" and that was that. But now even it doesn't help and I'm getting stuff like: Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 20074 frames in 5.0 seconds = 4014.652 FPS
Doesn't work under both EXA and glamor. Don't quite know when it changed. It does work however with bleeding edge X stack + mesa 10.7~git and "TearFree" option but with it 1) clock speed and voltage are always on maximum 2) mpv/bomi are slowly desynchronizing audio and video
