    Phoronix: Intel i915 Gallium3D Performance Examined

    Last week after a modern Intel Gallium3D driver was proposed for mainline Mesa, a side discussion ended up being ignited about making the i915 Gallium3D driver the default for older generations of Intel graphics hardware. To see where the i915 Gallium3D driver is at compared to the i915 Classic Mesa DRI driver, here are some new benchmarks from aging Intel i945 hardware.

    why does this guy keep running the exact same tests on some gay old quake3 games that no one plays?


    you do realize that just running gtkperf would be a million times better for this set and give us much more info right?

    That wouldn't prmote his testing suite, which he sells to game developers.

    That's because it really is unacceptable?

    If i ever find myself with any machine which uses PowerVR graphics I can assure you Linux is not going to go on it, period. I rather slap Windows on it (I have a Microsoft subscription which I pay out of my own pocket so my licenses are free) and enjoy a better user experience.

    In fact, my personal rule with netbooks is that Linux does not belong there unless there is a very good reason to do so, mainly because of battery life and heat. I know many people claim that they experience better battery uptime with Linux as opposed to Windows, but that is not what I am seeing in my personal machines.

    For notebooks Im a-ok with Linux because they are not meant to last the entire day on a single charge of juice and I generally lug my charger around when I have to bring it out with me for the day.

    http://www.mesa3d.org/envvars.html
    MESA_GL_VERSION_OVERRIDE for OpenGL Version
    MESA_EXTENSION_MAX_YEAR to limit advertised extensions by year they came out
    MESA_EXTENSION_OVERRIDE can be used for adding or removing advertised extensions e.g. MESA_EXTENSION_OVERRIDE=-GL_ARB_get_program_binary glxinfo

    Strange... In my gentoo tests on laptop with exactly the same configuration (old Acer Extensa 5210 with gma950, 2 gigs of RAM and cpu upgraded to T5600) gallium driver is from 10 to 30% faster, than classic.

    Someone from intel (ian or eric, i think?) posted a couple patches that brought the classic driver up to GL2.1 and a similar feature set to the gallium driver.

    It's really too bad that all the tests here were q3 based engines. I don't think that really tells us much of anything.
