LunarG’s KosmicKrisp, the Mesa Vulkan driver for Apple silicon, has achieved Khronos-conformant Vulkan 1.4 status. This follows its successful passage of the Vulkan 1.4 Conformance Test Suite (CTS), making it a fully conformant implementation for macOS. The Vulkan 1.4-conformant version of KosmicKrisp is now available for download via the Vulkan SDK, building on its prior Vulkan 1.3 conformance. This milestone is a significant step for Vulkan support on macOS. In addition to core 1.4 conformance, KosmicKrisp has added substantial support for non-core extensions and features, including Tesselation, Robustness2, and Multi-draw. LunarG also reported that "Performance of KosmicKrisp has tripled since it achieved Vulkan 1.3 conformance," with optimization work continuing.
