    Or just use the blobs.

    Not at every test the 750 Ti is new generation Maxwell GPU, in fact it would have to be 8xx generation and 780 Ti and 680 are Kepler

    Default 1920x1080 is easier to read 1080p(2k)

    I do think that with the 4k name resolution and in order to fast benchmark ...
    1920x1080 must me named 1080p (2k) and
    1280x720 must be named 720p (1k) and Phoronix should test ...

    1k + 2k + 4k resolutions

    Said this, OpenGL 4 is a great victory for NVIDIA drivers, and a great defeat for ...

    Xbox, PS4 and AMD APUs cheap Steam Machines

    So my actual CHEAP Steam Machine config should start with a CHEAP Nvidia 750Ti + any CHEAP AMD CPU configuration.

    Apitest use OpenGL 4.2+ and only ARB extensions, that is part of any 4.2 implementation .

    Just to point out... when they say "OpenGL", they mean our OpenGL implementation ;D.
    For example one thing that acceleratess OpenGl perf is ARB_indirect_parameters, ARB_shader_draw_parameter, ARB_bindles_textures, ... and all the other GL extentions mentioned in this presentation, will only give OpenGL 4.5/5 "a fast path" until the it is not the case, Nv may hav implementet it in ther prop. driver, but thas about it. To date OpenGl does not have this. Hope this gets implemented son and also get part of core specification.

    My main issue with FGLRX right now is I can't get my A10-7850K and R7 250 to crossfire
    My 6870s crossfire just fine. Wish AMD would fix this, my Steam machine would like some extra GPU power.

    Past that, not having any issues. Love my AMD cards. thinking of upgrading my CF HD6870s for an R9 280X.

    But looking in code i see there is actually some NV extensions used in apitest

    Code:
    GL_NV_shader_buffer_load
    GL_NV_vertex_buffer_unified_memory
    GL_NV_bindless_multi_draw_indirect
    And no AMD one i see there .

    @_ONH_

    Yep that is why i say _their_ implementation .

    No, the blobs work much better than the open source drivers, therefore when using nVidia hardware under Linux, I use the blobs.

    However the case is the opposite for AMD hardware.

    AMD and intel participated on that same conference (Approaching Zero Driver Overhead in OpenGL)
