    Great application. www.freecadweb.org
    I use it for several years with r600/radeonsi as testing/benchmark app.
    Sadly, one of their forum admins and GREAT tutorial author died in September. Rest in Peace, Roland!
    Addendum
    To put your FreeCAD work into the 'right light' (with GPU on AMD, Intel and Nvidia) use this: Photo-realistic rendering of FreeCAD models with CADRays

    https://forum.freecadweb.org/viewtopic.php?f=8&t=21339

    The used renderer was CADRAYS (OpenCASCADE) https://www.opencascade.com/content/cadrays

    @Michael: Wouldn't it be nice to have some benchmarks with it?

      I wonder what I'm doing wrong on my HD 6950: Updated the driver, checked OpenGL version:

      Code:
      $ glxinfo | grep OpenGL | grep version | grep core
      OpenGL core profile version string: 4.3 (Core Profile) Mesa 17.4.0-devel (git-b3e3cb9901)
      OpenGL core profile shading language version string: 4.30
      Removed the contents of ~/.cache/mesa and ~/.cache/mesa_shader_cache and the result is:

        Only some piglit runs missing and/or Dave have forgotten to send the right patch.
        Maybe Gert or I will prepare a patch for it.
        FIXED in Mesa git:

          airlied gerddie I really don't want to annoy you but it would be great to know if these are known problems.

            I don't have a cayman, only barts, and AFAIR there in the end all the piglits were passing.

            AI runs (mostly) fine - I have to force enable 4.3 and at some point sb is doing something strange to the shader so that I get lockups (but R600_DBUB=nosb) fixes this (bug reported), and some pieces have visual artifacts - like the radios change shape depending on the viewpoint.

              Thanks for your reply. In the meantime I opened a bug report: https://bugs.freedesktop.org/show_bug.cgi?id=104770

              Tried nosb but it didn't help here. HyperZ is disabled by default cause of various other issues.
