    Default Intel Linux Driver Almost Neck-And-Neck With Windows 8.1

    Phoronix: Intel Linux Driver Almost Neck-And-Neck With Windows 8.1

    Intel released a big Windows graphics driver update that for Haswell hardware now provides OpenGL 4.2 support -- while the Intel Linux driver just hit the milestone of OpenGL 3.3 support. To see how the latest Windows and Linux Intel graphics drivers compare, I ran some new benchmarks on Windows 8.1 against Ubuntu 13.10 to see how the performance pans out in various OpenGL game benchmarks and other graphics workloads.

    Wow, was not expecting them to be that good.

    Has there been any test using Source games? Aka "can I play dota2/tf2" with Intel integrated graphics yet?

    Thumbs up Kudos!

    Kudos to Intel developers! Keep up the good work!

    I tried to play dota 2 on a Laptop with an Intel HD4000 about 2 months ago. It was unplayable on Linux, while on Windows it works fine on low settings.
    However, I don't know if the HD4000 for the desktop is better than the laptop version.

    I have successfully tested Dota2 now on everything from GM45 to Haswell:

    - GM45 and Ironlake require mesa 10 (or git master) for correct rendering, but are unplayably slow even with everything turned right down.
    - Sandybridge and later both work correctly from 9.1.6 onward. Sandybridge is vaguely playable with everything turned right down; Ivybridge works reasonably well with mediumish settings (I'm limited by my own poor skill rather than the machine being too slow).
    - Haswell Iris Pro runs fine with almost max settings; requires 9.1.6+ for correct rendering, but mostly tested with 10 and master. I can't comment on performance of slower Haswell variants.

    Michael, you don't say what perf_bias setting you are using...
    ...on my Ivybridge system the BIOS sets it to performance mode, but the kernel switches to 'normal':

    [ 0.000203] ENERGY_PERF_BIAS: Set to 'normal', was 'performance'
    ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8)

    Despite the kernel log above, the "cpupower" utility is, I believe, the standard way to set performance modes:

    cpupower set -b performance

    This really helps performance here. I've no idea what the policy is in Windows, but it most likely sets it to performance mode when running on AC.

    All details can be found via Openbenchmarking.org.

    See the 21 way comparison results earlier as there's Haswell graphics and a CS: Source run.

    Core i5 3210M + HD4000 user here. Dota 2 plays fine with medium to max settings (720p, everything maxed except shadows and no AA). TF2 is playable with medium settings, but you really need low settings if you are expecting better framerates (important for online FPS gameplay).

    Edit: using Kernel 3.12.1 and mesa 9.2.3.

    i see that only the older unigine demos are used here.

    any news when the newer ones, like heaven 4.0 will work with intel systems (haswell)? in particular the shaders are not compiling and you see lot of errors on the console when starting the heaven demo and the demo on its own renders just plain white screen.
