    Phoronix: RadeonSI Gets Patches For OpenGL 4.5 Compat, Workaround For No Man's Sky On Steam Play

    Valve open-source Linux GPU driver developer Timothy Arceri has spent a lot of time in recent months improving the RadeonSI Gallium3D driver's OpenGL compatibility profile support. Now there are patches taking it up to par with the core profile context support...

    It's astonishing how far things have progressed in the recent years.

      It seems like only yesterday that we were hoping for performance parity.

      my fav memory was that one radeon bug where they were not using all the compute units on the chip (only using one cluster or something) that was a massive performance boost

        How difficult would it be to bring r600 to 3.3 compat?

          While RadeonSI certainly is the by far best GL driver for AMD hardware on Linux, I can't help but wonder if it wouldn't make sense to "port" it to PAL or even make a PAL-based open source GL driver. That way, it could be used on all platforms.
          Or AMD could go the ANGLE-route and just offer GL over Vulkan since they already have a good cross-platform Vulkan driver.

            There was a OpenGL over Vulkan driver in the works, but I think it's dead now.

            If only ANGLE supported OpenGL itself.

              R600 is at 4.4...

                No... that's core profile, and of course, it's only for cards that support OpenGL 4.x (RadeonHD 5000 and later) and officially turned on only for cards that support fp64.
                The last time I had my RadeonHD 4550 active, it was 3.3 core and 3.0 compat.

                  Hmm, so the patch set by airlied for soft fp64 didn't get merged yet?

                    Not difficult, that is as easy as installing Debian 7 ELTS and fglrx-legacy-driver Yeah, dropped blobby had that compat 6+ years ago

                    Real question should be - does nowdays anybody care to bring 10+ years hardware down to up to dropped blobby alike compat version, blah, blah

                    AFAIR R600 (with big R) was name of the chip found in a card of first HD so HD 2900 serie card which was not even capable of real 3.0
