    Phoronix: Windows 8 Outperforming Ubuntu Linux With Intel OpenGL Graphics

    In our benchmarks of Microsoft Windows 8, we have found that Intel's Windows OpenGL driver is generally superior to that of their open-source Linux graphics driver. Some progress has been made, but in today's testing of an ASUS Ultrabook bearing an Ivy Bridge processor, Linux has a ways to go for some games in matching the Windows binary performance and features.

    open source driver are forever just going to be FUNCTIONAL


    the closed source drivers are where they invest deeply in performance and really get the good code going


    don't expect intel to make a proprietary driver for linux so deal with it or buy nvidia

    That's like comparing the frequencies on a CPU. "How can a Athlon64 at 2.5Ghz be near a P4 at 3.5GHz? Obviously cheating."

    Raw Gflop numbers can be extremely misleading, and they are really only useful when comparing products within the same architecture.

    Unfortunately, that's not true in this case.

    Doubt it. Did it ever occur to you that the Linux driver has to things different with the Linux kernel and the Windows driver has to do it differently with the Windows kernel? It's just not only the driver itself that matters.

    And to be honest, 10% performance decrease is perfectly ok if that means I get to run Linux instead of Windows XP.

    I have no idea what this is about.



    The fact that closed source drivers does not make them cheat by definition.



    First you assert that closed source drivers cheat, and now you say that in the case of Intel they don't because they share some code for rendering.

    I don't think that the DRM intel driver part is shared with Windows.



    I just did, and you speak nonsense.

    The Intel open and closed source OpenGL drivers share no code whatsoever. They're completely independent.

If the driver wants to cheat will cheat, there is not technology available to measure quality of the picture. In fact when you have 2x GPUs you only have +50% FPS, that's is because the driver goes in quality and precision mode, same with double the shaders.

    The "cheating" is a bit different (and I don't know that Intel has ever been found to do it, though both AMD and NVIDIA have). The cheating is that the drivers can detect popular benchmarks or games and make changes to the rendered scene to improve performance.

    A famous example is when one driver cheated hard at LightsMark and did some special culling of the submitted geometry. Users who modified the benchmark found that if you turned the camera around while using said driver, you'd see broken geometry. On other drivers, you'd see the bits of the scene you'd expect.

    This is a popular tactic for both common benchmarks and newer games. It lets the driver authors publish much higher benchmark numbers for a stock configuration of the application, tricking users into buying their hardware/driver despite the fact that it is no faster in the general case or on app configurations they didn't cheat at, or that games might break if the user does something out of the ordinary on a cheated configuration.

    That's unlikely in FOSS drivers because all that code is a huge maintenance burden that only helps in marketing products, something that FOSS projects are not generally interested in. Also, spilling the beans on why a particular benchmark is so good kind of defeats the purpose of cheating at the benchmark in the first place.

    Again, there's no evidence I know of that Intel's Windows drivers are guilty of this at all.

    There is no reason to adjust the title. Windows GPU drivers are closed source. Linux GPU drivers are either open source or closed source. In the case of Intel, it's only open source. So there is no need to
    a) insult the author of the article
    b) suggest adjustment to the title

    I hope you don't ever reproduce...

    +1

    Lots of people do not like data so they want to degrade its importance.

    You CAN compare OpenGL perf just on one gpu :P
