    Btw, the Opera browser team has been working on OpenGL acceleration for at least two years now, but they still don't have it enabled by default. Their software renderer is still faster, more stable and consumes less resources than the hardware accelerated renderer.

    GPU acceleration is not some magic cure-all solution - especially when you have to go through something as unstable as OpenGL.

    Unhappy Help on enabling OpenGL 3.0

    I have some problems:
    Using OpenSUSE 12.1 x86_64.
    Code:
    death@triQuad:~/Desktop>uname -a
    Linux triQuad.site 3.3.0-16-desktop #1 SMP PREEMPT Mon Mar 19 10:17:31 UTC 2012 (7e199aa) x86_64 x86_64 x86_64 GNU/Linux
    
    death@triQuad:~/Desktop> R600_GLSL130=1 R600_STREAMOUT=1 glxinfo | grep Open
    OpenGL vendor string: X.Org
    OpenGL renderer string: Gallium 0.4 on AMD BARTS
    OpenGL version string: 2.1 Mesa 8.1-devel (git-5ac910c)
    OpenGL extensions:
    Using latest Mesa Master and compiled with:

    Code:
    ./configure --enable-gallium-g3dvl --with-gallium-drivers=r600 --prefix=/usr --libdir=/usr/lib64 --enable-{vdpau,xvmc} --enable-texture-float --with-dri-drivers=""
    Why I still have OpenGL 2.1?

    Issue is: There are old drivers on /usr/local/lib64/dri directory. Removed them and worked...

    You already solved your problem, but setting LIBGL_DEBUG=verbose is a good way to track down issues like these.

    Question Regression!

    Does anyone know if there is a regression over OpenGL 3.0?
    Because latest drivers gives me OpenGL 2.1 string on glxinfo, even if I use R600_GLSL130=1 flag...
    Also cannot find anything problematic with LIBGL_DEBUG=verbose but "libGL: Can't open configuration file /home/death/.drirc: No such file or directory." error message.

    OpenGL vendor string: X.Org
    OpenGL renderer string: Gallium 0.4 on AMD RS780
    OpenGL version string: 2.1 Mesa 8.1-devel (git-b2d6386)

    ???

    GL3 requires MSAA which is not yet supported. GL3 was mistakenly enabled
    without it initially. Dave has a branch with initial support which will be
    merged when ready:

    I could be wrong, but I think you also need GLX_ARB_create_context support. This was left out of X.Org Server 1.12, but will be included in X.Org Server 1.13.

    Unstable, he says... I've found, based on my past experience with DX10 while working at AMD (yes...) that neither is particularly stable when your drivers have issues and the API allows you to do stupid things with shaders and the like (and can be done on EITHER API, mind...).
