    Interesting, I thought they already had GL_ARB_debug_output ? Or was it previously only available in a debug context?

    That GL_AMD_pinned_memory stuff sound very good. Probably the same functionality that CUDA and OpenCL have had for while.

    They should try to update OpenGL’s memory model to be more generic like OpenCL/CUDAs so that it is easier to use advanced memory management alogrithims.

    I see the same error installing these drivers, but it works perfect. (I’m using RadeonPro instead of CCC)

    …………..:
    Yeah the H.264 hardware acceleration in VLC is broken for me too.

    But its not like you need it, h.264 only uses 1-2% on my CPU, and even old CPUs can play it without problems.

    Are you sure installing this is a good idea for my old gateway 450ROG laptop? The video card is a Mobility Radeon 7500. Every single time I’ve tried to install a better video drive, there are problems, like BSOD crashes. :(

    By the way, I’ve got the most recent driver update from Microsoft Update, 8.163.0.0 – Catalyst 0 (8-9-2005). Do you really think this newer driver is a good idea?
