    Default KDE 4.10 KWin To Properly Support AMD Catalyst

    Phoronix: KDE 4.10 KWin To Properly Support AMD Catalyst

    KWin, KDE's compositing window manager, will better play with the AMD Catalyst binary blob in the KDE 4.10 release by enabling direct rendering and the OpenGL 2.x back-end for those using the latest Catalyst driver...

    Martin Gräßlin, Thomas Lübking, and the other KWin devs rock. No other window manager comes close.
    Nice to see that AMD got OpenGL 2 working so soon. ;-p

    Direct rendering works only on KDE?

    A few days ago there was a KDE review request submitted by AMD's Jammy Zhou for white-listing the AMD Catalyst driver for KWin direct rendering.
    Why a application needs review request to use direct rendering with fglrx?

    2012 and AMD supports direct rendering.
    Haven't Nvidia supported direct rendering for years now?

    Either way, good to finally see it coming!

    By the way, does Kwin 4.10 work with Wayland?

    times ago they talked about openGL 3/4 support, where is it now? isn't openGL 2 old too?

    AMD has already been supporting direct rendering, but KWin couldn't use it for some reason.

    opengl is not directx meaning opengl 4 is not better or faster or cooler or pretiest than opengl 2, opengl 4 only provide extensions or improvements to support new techniques present in more recent hardware like tessalation for example.

    another thing is that opengl allows you to mix revisions[cuz mostly they are extensions] so the opengl 2 render engine can support FBO/VBO in dx9/10 class hardware for example and pbuffers for older hardware[not sure if dx8 class hardware can fully support FBO] and so on [ofc some features may require specific hardware or the use of especific extension from opengl X.x to work], in this case the important thing is support for opengl2 that allow you to use shaders, so later in time you can detect in runtime the GPU and add more capabilities present in that hardware or more complex/efficient shaders[<-- this is very simplified],etc.

    Well, that's kind of a funny situation. KWin now supports Catalyst. Catalyst no longer supports my graphics card. :\ Oh well, at least r600g is awesome.

    TextureFromPixamp was buggy under direct rendering, which is why none of the desktop compositers worked with it.

    Catalyst 12.6 was the release which fixed it.

    Compiz - uses indirect rendering only
    Gnome Shell - uses direct rendering only, which is why it was broken when you ran with fglrx
    KWin - made it optional and defaulted fglrx to indirect rendering since it was broken otherwise
