5 FPS and broken textures
Description Ondrej Zary 2010-03-21 06:49:27 UTC
Created attachment 34283 [details] 5 FPS and broken textures With radeon 6.12 driver, the performance in 3D games is very poor. Urban Terror that used to run at 40-50FPS is now unplayable with 5FPS. The textures are also broken (see attachment). In UT2004, the main menu was so slow that I was not even able to start a game.

3D driver issue.
Comment 4 Pauli 2010-03-21 08:25:51 UTC
What version of mesa are you using? What version of mesa was last to work?
Comment 5 Ondrej Zary 2010-03-21 14:24:09 UTC
mesa-7.7 (slackware-current) mesa-7.5.1 worked fine
Comment 6 Pauli 2010-03-22 11:38:34 UTC
I tested UrbanTerror with mesa 7.9 and kernel 2.6.34-rc1 (KMS). - No texture problems for me. - ramerates are definedly in slow side but not unplayable. I can have playable (35+ minimum) fps at 800x600 while 1024x768 is close to playable. 1024x768 has problem that minimum fps drops quite a lot (18 fps is lowest that I noticed) sometimes which is not good for shooters. Games is clearly GPU limited (cpufreq is selecting the lowest speed and cpu use stays around 50%).

Downgrading mesa to 7.5 while keeping X server 1.7.5 fixes the textures but not the low performance.
Comment 8 Ondrej Zary 2010-03-28 05:31:53 UTC
Downgrading X server to 1.6.3 and radeon driver to 6.12.2 (while keeping mesa 7.7) fixes the performance but not the textures. So there are two bugs, not just one.
Comment 9 Ondrej Zary 2010-03-28 06:15:01 UTC
6.12.3 (with X server 1.6.3) is OK, 6.12.4 (with X server 1.7.5) is bad.

Please try isolating it further by only changing the version of the driver or xserver. > So there are two bugs, not just one. They need to be tracked separately then.

Render correctly here and i tested two year ago performance with different drivers and was OKish for KMS: http://www.phoronix.com/forums/showthread.php?68319-Radeon-Gallium3D-A-Half-Decade-Behind-Catalyst&p=248042#post248042 And it is practicaly the same with current git mesa 10.2 :).
