    Default Radeon Gallium3D: A Half-Decade Behind Catalyst?

    Phoronix: Radeon Gallium3D: A Half-Decade Behind Catalyst?

    What happens when you pull out some vintage computer hardware and run the latest Linux software as well as go back and run some of the oldest software available? Well, in the case of systems with antiquated R300-era ATI Radeon graphics, you are left with a downward slope in performance. Not only is the latest open-source Radeon graphics driver not always performing as well as an ancient Catalyst driver, but also the power consumption of the latest Linux code remains on an incline.

    Try making these same tests, on a desktop environment other than Unity, to compare newer versions of drivers with the older.
    In my case, when I switched from Unity 3D to XFCE, I got a significant performance improvement when running Skyrim, through Wine.
    I can say that the game that was unplayble on Unity, become playable on XFCE, something comparable to the Windows performance.
    My system is:
    AMD Phenon X4 2.4GHz, 4GB DDR2 800MHz and Nvidia GeForce 8600 GT (Driver 280.13).

    There is tremendous variation among older and newer ATI cards in terms of how they perform using free and binary ATI drivers... what makes you suppose your experience using Nvidia is in any way relevant?

    AFAIK Hyper-Z is not enabled by default on r300g. Marek wrote onto the mailing list that there are still some bugs he could not figure out, hence it is disabled.

    What I'm suggesting is that Unity is a heavy weight Desktop and it can compromise the performance of running applications.
    If you see the chart on the benchmark article, you will find out that along side you are comparing different device drivers, there is also a difference in the desktop environment.
    In my opinion it is not fair compare software running on different environments.

    I'm not saying that it will work for Radeon hardware, but in my experience, I always found that one of the huge performance bottle neck in Ubuntu, was the Unity interface.
    That is why I've switched to Xubuntu, in this last release cycle of Ubuntu.

    This comment is too short, so I'm assuming it had nothing of value.

    Summary: Mesa is a miserable failure.
