--- Comment #2 from Matteo Bruni matteo.mystral@gmail.com --- This bug as expressed in comment 0 doesn't mean anything specific so your objection is perfectly valid, Bruno.
Given what I know about Vulkan (which is admittedly not much) I can think of two "steps" for "supporting" Vulkan in Wine. The first step would be to make a wrapper DLL to forward Vulkan API calls from Windows applications to the native (e.g. Linux) Vulkan lib, pretty much in the same way as we currently do for opengl32.dll. It's probably not entirely trivial to do but I guess much of the same infrastructure we have for OpenGL can be reused / reworked for Vulkan.
Then we could ideally use Vulkan as another option for translating D3D APIs in addition to OpenGL. This is going to be hard work and I don't see it happening any time soon. I also think this is what the OP meant.
I guess you can update this bug to target either of those two options specifically (or maybe some other kind of "support" we could add). As it is the bug doesn't seem useful.
