    Phoronix: Vulkan WSI Support Is The Latest Being Worked On For Wine

    Following more Wine Vulkan code being merged and the first milestone being achieved of vulkaninfo working, Roderick Colenbrander has submitted his latest patches in the bring-up of Vulkan support under Wine...

    Can somebody dumb it down (while still being a little technical :P ) and explain why does vulkan need to be worked on for wine?

    I mean vulkan is nativelly supported in linux right?

    Can't wine just wrap the windows specific calls and "pass through" all the 3d graphics api stuff if its vulkan and not d3d?

      That is exactly what these Vulkan patches for wine do. They don't implement a hardware driver, they implement a passthrough driver which uses the system's Vulkan driver, while translating the Windows-specific bits to something that Linux Vulkan drivers understand (i.e. the WSI extensions that are mentioned in the article).

        So essentially we are looking at similar FPS performance on full-screen 3D games given that the hardware is the same the CPU is not 100% utilized by the game and that the game runs vulkan?

          Barring driver performance difference between Windows and Linux, yes.

            Why would there be a driver performance issue when the hardware(GPU) is the same and the api is the same ?

              Because the driver is not the same.

                The windows vulkan driver still fairs better then RADV by a decent margin (20-30%). RADV is coming along however, won't be long before its on par with windows performance.

                  Do you have any benchmark results? I looked for them but found none.

                  On my Vega I don't see performance differences between RADV, AMDVLK and Windows...
