Khronos has shipped the provisional version of the Vulkan Portability Extension version 1.0 and it is shipping today in both MoltenVK and gfx-portability. If you want to try out the extension, build MoltenVK or download gfx-portability-0.8.1 and redirect the Vulkan loader to a JSON manifest using the regular ICD logic, as if MoltenVK and gfx-portability were native Vulkan drivers. Learn more about the Vulkan Portability Initiative and explore the value of layered implementations to the graphics community in this blog.
