    Phoronix: Gallium3D Patches To Help GRID Autosport, Metro Redux & More

    For those having some extra time today to help test out some new Mesa patches or just curious about what's on the horizon, Nicolai Hähnle of AMD has posted some Mesa state tracker patches for benefiting several modern Linux games...

    This patch will fix the regression found recently on these games or besides fixing the regression, it will improve even more the performance?

      Interesting. I bought the Metro games because of their Linux compatibility, but I played them on Windows because they were pretty much unplayable and graphically glitchy. I think I recall there being other issues too, like not supporting 5-button mice or surround sound, but I could be wrong about that.

        "reducing stalls"

        The single most annoying thing in both open and closed AMD drivers. Definitely worth checking this out.

          it will not fix regression, it will accelerate unaccelerated path

            For the lazy: https://patchwork.freedesktop.org/series/7349/

            Is freedesktop's git repository unusably slow for anyone else?
            https://cgit.freedesktop.org/mesa/mesa/log/

            edit: Just changed to https://github.com/mesa3d/mesa instead

              Really? I played MLL and M 2033 Redux on a AMD 6850 HD using catalyst and I think I also tried the radeon driver in the case of Redux faking OpenGL 4, and I don't remember major glitches. It was well playable.

              Extra mouse buttons beyond 3+wheel didn't work, that's true, don't know about surround.

                Wanted to try whether csgo was better, but of course it segfaults:
                https://gist.github.com/ChristophHaa...f4577d6e5923f6

                Wanted to try xonotic for a simple test:
                LLVM ERROR: branch size exceeds simm16
                Same with unigine-heaven and 0ad.
                I wonder if I merged something wrong or llvm is just broken right now. Not sure what exactly this is http://reviews.llvm.org/D20227
                edit: Downgraded llvm from 269966 to 269746 and xonotic works. So it's llvm *sigh*. csgo also starts again.
                edit: csgo on HD 7970M still drops below 60 fps all the time while GPU usage is somewhere between 40-60%. So it doesn't help for that game.


                Edit: Tried to make a video with metro 2033 redux:

                But it was cut short by my laptop being crashed by the (probably) ref counting bug in the kernel that has been unfixed for over a year:
                Code:
                [183492.599713] BUG: unable to handle kernel paging request at ffff80025b85f278
                [183492.600833] IP: [<ffffffff8149cf16>] reservation_object_add_shared_fence+0x176/0x2f0
                References:
                csgo native: https://bugzilla.kernel.org/show_bug.cgi?id=96721
                csgo nine: https://bugzilla.kernel.org/show_bug.cgi?id=103561
                (possibly) steam client: https://bugs.freedesktop.org/show_bug.cgi?id=92258
                Still drops to ~25 fps on HD 7970M when many NPCs are visible and a lot with lighting and shadows goes on.

                  it's fantastic, up to 50% performance boost with Grid Autosport(FullHD Ultra set 23->34 fps).

                    X rebirth feels a lot smoother between highways too, so far so good in Tahiti
