    Yes, their OpenGL driver has always been slow. It gets somewhat better at high resolutions but remains vastly inferior to other implementations. At least, the Vulkan-over-Metal implementation seems to perform at almost native performance, which basically means that the Metal driver itself must be decent.

      Vulkan is not faster than OpenGL on Windows, and is actually slower on Linux?

      I guess it requires actual programming skill to use instead of hand-holding and the OpenGL drivers are probably optimized af. Most DX12 games also tend to be slower than DX11, which is not the fault of the API, but the game devs who just now realized they need to do more than just plug a few libs together.

        Hi Michael.

        Will you be doing some intel gpu testing for same scenario (mac laptop)?
        The Feral Reise of Tomb Raider port on Mac is supported on Intel (iris) gpu, while linux port is not supported

        It would be interesting to see how intel gpu works across platforms.

          Check the hundreds of benchmarks all these years in this site and tell me something where OSX is not slow...

            DOTA 2 is something of a special case when it comes to Vulkan. It's essentially a DX9 title that's been ported to everything else, and for that reason it doesn't particularly take advantage of a lot of more recent/advanced features.

              Would have been good to have seen the directX numbers on windows too

                Even if it's only as fast as the alternatives on some platforms, being able to target Windows, macOS and Linux on same Vulkan codebase and get good performance on all platforms sounds impressive

                  They have a long history of shittifying old stuff to make new stuff look better, nothing unexpected here.

                    fixed

                      Quick, lets bash Apple for not supporting:
                      - Vulkan
                      - modern OpenGL
                      - directX
                      - Wayland
                      - whatever
                      - insert random Linux related project
