--- Comment #27 from darkbasic darkbasic@linuxsystems.it --- Power state high doesn't help.
qvdpautest + 3.14-rc0 + AUTO + KWIN OFF:
MPEG DECODING (1920x1080): 8 frames/s MPEG DECODING (1280x720): 9 frames/s H264 DECODING (1920x1080): 8 frames/s H264 DECODING (1280x720): 8 frames/s Profile unsupported. MPEG4 DECODING (1920x1080): 8 frames/s
qvdpautest + 3.14-rc0 + HIGH + KWIN OFF: the same
qvdpautest + 3.14-rc0 + HIGH + KWIN ON + glxgears:
MPEG DECODING (1920x1080): 77 frames/s MPEG DECODING (1280x720): 117 frames/s H264 DECODING (1920x1080): 51 frames/s H264 DECODING (1280x720): 90 frames/s Profile unsupported. MPEG4 DECODING (1920x1080): 71 frames/s
Fortunately I noticed a great improvement with 3.14: I don't have the huge lag before the start of the benchmark and glxgears doesn't freeze anymore like in http://www.youtube.com/watch?v=BDhB61U9S0A
