vaPutSurface (X11) waits on v-sync?
With the minor nit that for a long time the intel X driver didn't
implement this on snb/ivb, resulting in tearing. But with kernel 3.8
and latest xfree86-video-intel when using the SNA backed it should
work.
The result is that with xf86-video-intel GIT from yesterday,
libva-intel-driver-1.0.18, libva-1.1.0 and kernel-3.8.2.
vaPutSurface does no longer wait on vsync.
With SNA:
X &; export DISPLAY=:0.0; putsurface -> 75.29 FPS
CTRL-C
Seems to be random, I just updated GIT to have a debug version
for the backtrace and now its reporting 50.20 FPS.
