LunarG's KosmicKrisp, a Mesa Vulkan driver developed for Apple silicon, has recently achieved Khronos-conformant Vulkan 1.4. The driver successfully passed the Vulkan 1.4 Conformance Test Suite (CTS) and is now available through the Vulkan SDK. This marks a significant advancement for Vulkan support on macOS, building upon its prior Vulkan 1.3 conformance. Substantial support for non-core extensions and features has also been integrated, including Tesselation, Robustness2, and Multi-draw. LunarG reports that KosmicKrisp's performance has tripled since it achieved Vulkan 1.3 conformance, with optimization work continuing.
