    This commit is not meant to speed up glxgears.

    It speeds up QuakeLive from 2fps to 60fps here.

    That's what you should be testing.

      Well, obviously, nobody's really interested in speeding up glxgears in itself, but since most people here seemed to get much higher fps, I figured I could test that, since I don't play games and thus don't plan to test QuakeLive.
      Well, never mind. I was merelly curious, I'm not that concerned.

        glxgears didn't change at all for me either with this patch. But QuakeLive did.

          I'm using kernel 2.6.33rc4 on both, libdrm, mesa and xf86-video-ati from git but still 1.6.2 X server on both.
          Would upgrading to a more recent Xserver would make a difference?
          As I said before, this code will not affect gears performance. It will only improve performance for applications that use glCopyTexImage or glCopyTexSubImage. glxgears does not use textures at all.

              Hm...after updating the kernel, libdrm, mesa and xf86-video-ati to the current git release vsync (that comes with irq support) doesn't work anymore. Is that related to blit support?

              I didn't found an error in dmesg and xorg.0.log.

                the blit code has nothing to do with vsync.

                  Ok, that was just my assumption cause it worked before updating.

                    Anyone knows if this will be picked up by Ubuntu Lucid? (or whether I'll need to compile it? I hate to mix packages with manually installed binaries). Thanks in advance!

                      Almost certainly not. Lucid is a long term support release, and I cannot imagine them updating to mesa 7.8 a bare month before release.
