https://bugs.freedesktop.org/show_bug.cgi?id=34493 --- Comment #7 from Dave Witbrodt <dawitbro@xxxxxxxxxxxxx> 2011-04-11 20:15:46 PDT --- I have been away from Linux and testing radeon support since the Japan crisis began. Updating to Mesa 7.11.0-devel, commit a26121f3, caused the same slowdown I had observed before: min/max framerate in 'torcs' dropped from 28/54 fps to 17/34 fps. I was planning on restoring local packages of my last fast-working Mesa, but decided to rebuild my entire X stack against my newly updated kernel (updated from 2.6.38-rc8 to 2.6.38.2). To my shock, I found that replacing xorg-server 1.9.99.903 with 1.10.0.902 and updating the radeon driver to the latest git version, 6.14.99-devel, commit cc7d1fa3 -- both built against the Mesa mentioned above -- improved Mesa performance in 'torcs' dramatically. It is no longer as consistently high as I was getting, but gives me 17/54 fps. I also notice that another test program, 'prboom-plus', has dramatically improved performance all around. As a result, I am abandoning my local git branch where I intended to pin down the exact cause of the performance changes -- I haven't touch it for 7 weeks anyway -- and start following the Mesa HEAD again. Sorry for the false alarm. It appears that Mesa changes alone were not to blame for whatever performance problems I was experiencing. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
