    Phoronix: Mesa 19.1 To Expose EXT_gpu_shader4 Support

    While it's not looking like Mesa 19.1 will end up exposing OpenGL 4.6 capabilities, it is picking up various other extensions including some prominent several year old extensions like EXT_texture_buffer_object and the decade old EXT_gpu_shader4...

        If I recall, there were a couple old ones that had optional support for this. But it was never that compelling. If it was, we would have done it 5 years ago when Chris started this project.

        I think the main reason for doing this now is to have more of a consistent feature set between Mesa and closed drivers. There are probably some old enterprise type apps using it, too (if I had to guess).

          NVIDIA ever opens up it's OpenGL's extensions, or no way?

            Black Mesa wasn't starting without this extension. Don't know if they still rely on that but I think they fixed it in the beta branch.

            Minecraft seems to be another one. https://bugs.freedesktop.org/show_bug.cgi?id=110431


            I say it's great they finally added this, even it's way too late...

            Thanks for the work.

              We have had people filing bug reports about this extension over the years they have generally been closed as not our bug. Minecraft and Substance Painter are mentioned in this [1] recent bug report, Black Mesa required it although recent beta versions no longer do. There are probably windows apps that use it which makes it more important now that wine is starting to work really well.

                I haven't heard of that game. Is it on Steam?

                    Was it superseded by newer extensions? Like the ones from 3.3 became another when OpenGL went to 4.0?
