That is correct, my morning brain mixed it up because of writing of MoltanVK started me off on Metal on Vulkan. I bought it up because of the general topic of Vulkan and Metal, not because of gfx-rs itself. MoltanVK deserves a mention due to Khronos Group sponsoring it.

This is sadly a common misconception, partly due to Khronos messaging. MoltenVK is sponsored by Valve, not Khronos. Both gfx-rs and MoltenVK are working in Vulkan Portability TSG, and both are promoted by the slides/talks if you read carefully. MoltenVK just gets more attention because it's packed by LunarG and used in Dota2.

  I saw MoltenVK under KhronosGroup control here, which led to my confusion once more: https://github.com/KhronosGroup/MoltenVK https://github.com/KhronosGroup/MoltenVK And yea, the messaging is confusing because of this line on their site: > As a first deliverable from the Vulkan Portability Initiative, Khronos members Valve, LunarG, and The Brenwill Workshop have released a collection of free and open source set of tools, SDKs, and runtime libraries to enable Vulkan development on macOS and deployment on macOS and iOS platforms Source: https://www.khronos.org/vulkan/portability-initiative https://www.khronos.org/vulkan/portability-initiative That led me to think they’re sponsoring it. It looks like MoltenVK was created by The Brenwill Workshop.

    KhronosGroup github organization may be hosting projects of Khronos members that align with Khronos mission, but they aren't necessary the deliverables of any working groups and thus can't be official/sponsored. > Khronos members Valve, LunarG, and The Brenwill Workshop have released It's like saying "W3C members Facebook, Instagram, WhatsApp have released ..." :D Basically, Valve released something that they want to look like it's supported by Khronos. And this trick worked - now everybody believes it to be a Khronos product.
