For anyone who don't read IRC logs - it turns out it regressed only on
my box, because I have page flipping disabled (due to page flipping
being very buggy here, see
https://bugs.freedesktop.org/show_bug.cgi?id=42398), which forces gpu
context switch on every frame - even with (OpenGL) full screen apps.
And this patch slows down context switches. So, can we disable xfers
in ctxprog only when page flipping is enabled? Or is there any other
option? Marcin
Hmm, it isn't logical yet. To test for performance regression, I
launched the well known context switch test that is glxgears and only
found a performance decrease of 1%.
I'll test with pageflip disabled though and see for myself.
Anyway, we'll do something about it. I just hope that most cards don't
have this problem. This is clearly an hw regression.
