Performance decrease after upgrade to Gallium3D and Mesa 7.9

Hello,

I upgraded today to the new kernel 2.6.36 and mesa 7.9-1 and the performance of my video card (x1400) decreased significantly when compositing is enabled in KDE4. It takes a long time to move windows, the window minimization animation is not as smooth as it used to be with mesa 7.8, etc. If I disable compositing everything is fine.

Xorg.0.log doesn't show anything unusual.

I have KMS enabled, glxinfo gives:

direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on RV515
OpenGL version string: 2.1 Mesa 7.9
OpenGL shading language version string: 1.20

Does anyone with an ATI X1400 have similar issues, or know if this is a known problem? Thanks

Hi,

Switch to the Xrender backend.
I have an x1950 that uses R300g too and using glx has never been smooth, xrender is.

xrender is definitely better but still worse than the old r300 with the opengl backend. Did you see any change in performance when you upgraded the video related packages recently?

I don't understand why they moved to extra. We're experiencing the same problem

upstream bugs/regressions don't stop stuff moving to the repos unless it severely breaks something

Guys, I would try -git combinations:

1)xf86-video-ati-git
2)mesa-git
3)xorg-server-git
4)kernel26*-git

If I tried the -git stuff I could never get back to 7.8 version, since there are 7.9 in [extra]

-git now is (almost) 7.10. Try it.

7.8 will be in your pacman cache

Re: Performance decrease after upgrade to Gallium3D and Mesa 7.9

I would suggest trying disabling vertical sync with

export vblank_mode=0

in .bash_profile or somewhere.
I have noticed that some programs run significantly better with no vsync. But I am on r600c and I use mesa-full/xf86-video-ati-git etc.

I'm very new to archlinux. How do I compile/install the git packages? I was looking for an entry in the archwiki pages but I must be blind, I didn't see any. Thanks

I do pacman -Scc every time after the upgrade. Bleeding edge without regrets fan, you know

I ended up recompiling mesa without gallium using ABS. I installed the resulting libgl, mesa, and ati-dri and everything seems to be fine now. Thanks all for your suggestions.
