Description Kees Cook 2008-12-29 11:37:59 UTC 
Created attachment 21549 [details]
tremulous sysprof log

video-intel is 2.6.99.1+git20081220.d8e89b26
libgl1-mesa-dri is 7.2+git20081221.f83f5ec8
kernel is .28-rc9
libdrm2 is 2.4.3+git20081216.c86d431f

When forcing on UXA/dri2, there is a large performance regression in 3d rendering when playing the game "tremulous".  Attached is sysprof log of a sample run.
Comment 1 Eric Anholt 2008-12-30 16:01:40 UTC 
(notes from irc: sysprof showed no driver time but lots of app and X time -- likely fallback to sw rendering but the bug report is missing xorg.conf, xorg.log, and dmesg)

Kees, please provide the info requested by Eric. Thanks.
Comment 3 Kees Cook 2009-03-02 16:34:52 UTC 
It will take me some time to reproduce the issue.  I have since backed out all the bleeding-edge versions of things to get general stability back to my system.  I will report when I'm more update.  Thanks!

Feedback timeout (2 months).  Works fine on my GM45.
