    Re: Intel GMA HD and OpenGL

    How is that an option?

    If the driver is crap and the hardware is incapable then surely OS will make absolutely no difference whatsoever? Even if the GNU/Linux driver is somehow anyway better, the...
  2. Re: How prone is Intel to updating their graphics driv

    The drivers get updated all the time and developers are responsive to bug reports.

    Re: Official feedback on OpenGL 4.2 thread

    Ok, I didn't notice how few deprecated features there are in the spec (I found only line width and some queries).

    Re: Official feedback on OpenGL 4.2 thread

    I wish we could get a "clean" version of the spec - one with all deprecated functionality removed.

    Of course it is.

    That's because their Windows drivers suck. The situation is better on GNU/Linux.

  8. Re: Ensure OpenGLapplication is using H/W acceleration

    Invoke glxinfo, check the renerer string, if it says Intel, you've got hardware acceleration, if it says software, you don't.

    E.g. on my system:


    > glxinfo | grep renderer

    Re: Extensions to promote to ARB/core

    Another reason for us to not want them to put S3TC support into core GL: It would lock out newcomers (which won't ge a license) and thus work against innovation.

    Re: Error on compressed 1D texture

    You're explicitly specifying GL_COMPRESSED_RGBA_S3TC_DXT5_EXT, which does not support 1D textures. Even if your card supports some compression system for 1D textures your code won't work.

    GSL has control structures like if/else for, etc. AFAIK SM3 added branch instructions which are needed for such control structures. OR in the words of the main Mesa developer, as posted on a Mesa...

    To see it seems it's just the other way round: GLSL in Mesa is there (and works on newer hardware like the GMA965), but the GMA950 hardware does not support SM 3.0, only SM 2.0. There's an Intel...
