    If anyone is seeing regressions, please file bugs:

    and attach your xorg log and dmesg output. Also, if you could narrow down the problematic component (kernel, ddx, mesa) and bisect it, that would be really helpful.

    GL_RENDERER = Gallium 0.4 on AMD REDWOOD
    GL_VERSION = 2.1 Mesa 8.0.1
    GL_VENDOR = X.Org

    814 frames in 5.0 seconds = 162.771 FPS
    783 frames in 5.0 seconds = 156.577 FPS
    772 frames in 5.0 seconds = 154.280 FPS
    717 frames in 5.0 seconds = 143.378 FPS
    673 frames in 5.0 seconds = 134.488 FPS

    I use Fedora 17 and a Radeon 3200 IGP. On the current kernel version 3.3.0-0.rc7.git2.3.fc17.x86_64 I don't have any issues with a performance regression. On a rc6 kernel I had much worse fps than ussually in a game, but I didn't test it much, because I avoided this rc6 kernel then. I had 1-2 fps when I used this kernel, and ussually I get around 15 fps with the free Radeon driver (game: regnum online).
    It helps also to use a kernel without debugging options enabled. With this option enabled my system freezes sometimes. I have no idea if Beta TC2 already used the kernel version above or a older version with debugging enabled.

    Whoops, sorry... I was responding to DaemonFC, should have quoted for clarity. Sounded like he was seeing a much greater regression than you did.

    It was all correct. The data is available from OB but if the OpenGL renderer was wrong it would have been reported to the system table, etc.

    Regarding Fedora 17, there seems to be a recent and rather severe regression for my Radeon HD 5670. even glxgears can only manage about 100 fps. I know that's not a benchmark per se, but damn...

    Games are unplayable, kwin is barely even usable.

    Do you know what the story is with that and when it might be resolved?

    I checked it out using the Beta TC2 ISO.

    My HD7970 is currently getting 0 fps with the open source graphics stack, so I'd be happy to see performance numbers like Cayman's World of Padman -- that would be infinity times better than what I have now.

    Also, it's very interesting that you think that "The results for Nexuiz are more interesting than Nexuiz". I would tend to agree; Nexuiz is not a very interesting game, but the performance results that you produced, using it, are very interesting indeed. I think you might have typoed this and meant to say something like "The results for Nexuiz are more interesting than Doom 3", but that would be eliding the very deep philosophical point you validly made about the level of intrigue associated with playing the game Nexuiz versus benchmarking it.

    Michael, what about the mesa daily benchmarking you were willing do deploy? Is there any news?
    It seems we really need such a thing...
