@Tom: I don't want to start a flamewar, but:

§1: I have never used GPU-intensive games in DOS and Windows (were
Commander Keen, Pushover and Many Faces of Go... GPU-intensive?), I have
never used GPU-intensive games in Linux (unless gnotravex and quarry +
gnugo + grhino qualify for that), and I WILL NEVER INSTALL NOR USE "TRUE
GAMES" EVER!

Computers were not invented for this kind of games (now, chess is
another story). I don't tolerate "true" computer games in my sight.
GAMES ARE *NOT* A VALID BENCHMARK, except for gamers!

And I don't trust the IQ of hardcore gamers. Sorry to the offended guys.

§2: Yes, glxgears is *not* a benchmark. OK, instead if just counting how
many times you can rotate some gears on the screen, it might actually
count the number of frames, because of the call to glutSwapBuffers(); in
gears.c, in the function draw(). From the doc:"The update typically
takes place during the vertical retrace of the monitor, rather than
immediately after glutSwapBuffers is called. ... Subsequent OpenGL
commands can be issued immediately after calling  glutSwapBuffers, but
are not executed until the buffer exchange is completed."

However, please note that this is not normal to have the frame refresh
rate *severely* changed by a KERNEL update, while using a same version
of the video driver!

§3: Performance regressions can be seen in full-screen Flash too, and
regressions are unacceptable. Watching a video or a Flash is not like
gaming, yet it's necessary for a desktop/laptop usage.

§4: EXA, EXA, EXA. The bug report is not about UXA. UXA is "not ready",
therefore it does not exist.
