KosmicKrisp is the effort led by LunarG for developing a modern Vulkan-on-Metal driver for Apple systems within Mesa. This modern alternative to MoltenVK continues progressing well and now enjoys Vulkan 1.4 conformance and its performance continues inching closer to that of the native Apple Metal API.
