    Default FC5 and glxgears

    First of all, I know that glxgears is not a benchmark. But I have installed the new drivers - 8.28.8 - and rebuilt my kernel according to the instructions. glxinfo and the ATI control both show that "Direct Rendering" is enabled. Despite that, glxgears shows a frame rate of only 250 FPS. It is my understanding that it should give a rate of at least an order of magnitude higher.

    Any suggestions?

    Thanks.

    Using a X1400, the 8.28.8 drivers (as with past drivers) is also about 250 FPS. Had you noticed more frames from glxgears in the past? Had you noticed any performance change with fgl_glxgears?

    $ glxgears
    1218 frames in 5.0 seconds = 243.506 FPS
    1250 frames in 5.0 seconds = 249.998 FPS
    1250 frames in 5.0 seconds = 249.998 FPS
    1252 frames in 5.0 seconds = 250.398 FPS

    Before the upgrade, the rate was about 200 FPS. fgl_glxgears gives about 500 FPS:

    fgl_glxgears
    Using GLX_SGIX_pbuffer
    2283 frames in 5.0 seconds = 456.600 FPS
    2441 frames in 5.0 seconds = 488.200 FPS
    2453 frames in 5.0 seconds = 490.600 FPS

    It's worth noting that the animation is extremely fast and smooth. Before the upgrade, there were pauses and it was "jerky". So, it's obvious that it has caused some improvement, but it seems slow compared to other comments I've seen about glxgears FPS rates.

    Thanks.

    Glxgears (yes it's not a benchmark, got it) scores prior to the 8.27.10 driver:

    approx 1200fps

    Glxgears for 8.27.10 and 8.28.8: 242


    Fgl_glxgears prior to 8.27.10:

    approx 350

    Fgl_glxgears for 8.27.10 and 8.28.8: 268


    System: Hp/Compaq nc6000 w/ Radeon Mobility 9600 64MB dedicated.

    Pretty much both have gone down.
    Linux Game Native Versions: Ut2k4 scores have gone up slightly, Doom3 has gone down slightly.

    The above is using Suse Linux Enterprise Desktop 10

    Hope this helps.

    Default Frame Rates

    That's interesting. I was reading notes by other people, quoting frame rates between 1000 and 3000. So, when I ran it on mine and saw that it was around 500 - at the best - I thought I must have a serious problem. But, it sounds like my numbers are not unreasonable.

    Thanks.

    I'm getting:
    3454 frames in 5.1 seconds = 679.893 FPS
    3400 frames in 5.1 seconds = 672.152 FPS
    3480 frames in 5.1 seconds = 683.893 FPS
    and that is with the xorg radeon driver with software openGL (mesa)

    It seems the new driver works for xpress 1x00. No mention of xpress 200 though. Another one of those long unfixed bugs

    Michael, do you have any kind of information concerning the expected timeframe/release for a driver that supports the GL_EXT_texture_from_pixmap extension?

    I have yet to receive any official word regarding that OpenGL extension from ATI. I would personally hope the support is delivered by/with the 8.30 fglrx drivers.
