    Phoronix: Dolphin GameCube/Wii Emulator Lands Its Vulkan Backend

    The past few months we've written a few times about the Dolphin Emulator working on a Vulkan back-end. Dolphin is an open-source project providing cross-platform emulation for Nintendo's GameCube and Wii games. That back-end has now been merged to the mainline code-base...

    Damn these guys aren't kidding around implementing it this fast.

      Since dolphin is very CPU intensive on a single core it would be very interesting to see benchmarks of OpenGL vs Vulkan performance differences on a few games.

        This. Dolphin is a excellent test subject for Vulkan vs OpenGL performance IMO.

          ElectricPrism johanb unfortunately not aware of any automated capable dolphin tests.

            Michael it shouldn't be too hard to set up automated dolphin performance tests. You can use a lot of the TAS features like savestates and input playback.

            For me on NVidia Pascal, there is no noticeable difference between Vulkan and OpenGL.
            But I heard from AMD users that it's a quite nice speed increase for them.

              Just read the pull request. The author doesn't give any exact numbers, but the improvements he claim seems to be similar to other Vulkan/DX12 games.

              - Performance in my brief testing is slightly above OpenGL on nVidia
              - AMD seems roughly ~25% faster compared to OpenGL in some scenarios (apart from needing the dualsrc blend fallback)

                Gonna have to see if vulkan works on os x. I doubt it.

                  There is no Vulkan on OSX. Apple instead went with their own API.

                    i tested the vulkan backend before its merge
                    on intel the performance is a bit lower, but its driver fault for not having hiz,guarband clipping...
