Submission declined on 12 April 2026 by Flexagoon (talk).

This draft's references do not show that the subject meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that:

provide significant coverage: discuss the subject in detail, not just brief mentions or routine announcements;
are reliable: from reputable outlets with editorial oversight;
are independent: not connected to the subject, such as interviews, press releases, the subject's own website, or sponsored content.

Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia.

This draft is not adequately supported by reliable sources. Wikipedia's verifiability policy requires that all content be supported by reliable sources.

Reliable sources include: reputable newspapers, magazines, academic journals, and books from respected publishers.
Unacceptable sources include: personal blogs, social media, predatory publishers, most tabloids, and websites where anyone can contribute.

Replace any unreliable sources with high-quality sources. If you cannot find a reliable source for the material, it should be removed.

KosmicKrisp is a Vulkan driver which translates Vulkan API calls to Apple’s Metal framework for macOS, it is a part of the Mesa 3D framework.

There are some limitations compared with a native Vulkan implementation that require workarounds

Timeline

2024

November:

LunarG formally starts the KosmicKrisp project as a new Vulkan‑to‑Metal driver built inside the Mesa Vulkan driver framework, targeting Apple Silicon on macOS. Design goals included full Vulkan 1.3 conformance without Vulkan Portability compromises and close integration with Mesa tooling and NIR.

2025

February:

First compute tests pass in KosmicKrisp, confirming the basic Metal backend and Mesa integration work.

March:

First graphics “triangle” rendering passes, marking the first visible graphics output via Vulkan-through‑Metal.

April:

Basic demos such as vkcube run successfully, validating the core pipeline and synchronization model.

Conformance and Public Debut

May:

First complete run of the Vulkan Conformance Test Suite (CTS) finishes, uncovering API‑level bugs and edge cases.

August:

KosmicKrisp is publicly showcased at SIGGRAPH 2025 with a demo on M‑series hardware, emphasizing its role for Vulkan‑based workloads on Apple Silicon.

September:

KosmicKrisp achieves 100% Vulkan 1.3 CTS pass internally; the stack is now considered technically conformant for Vulkan 1.3 on macOS 15+.

October:

LunarG submits the driver to the Khronos Group and announces that KosmicKrisp is a Khronos Vulkan 1.3 Conformant product for Apple Silicon.

2026

KosmicKrisp is merged upstream into the Mesa 3D graphics library as a shipping driver, appearing in Mesa 26.0+.

Mesa documentation marks KosmicKrisp as a Vulkan‑conformant implementation for macOS on Apple Silicon, running on top of Metal 4 and requiring macOS 26 and up; no iOS support is present yet, though A14 Bionic hardware was considered in design.

LunarG presents KosmicKrisp at Vulkanised 2026 (San Diego), outlining a roadmap that includes:

Vulkan 1.4 conformance

Tessellation and geometry shaders.
Performance optimization passes.
Debug‑tool integration (e.g., RenderDoc).
Future support for iOS on A‑series GPUs.

There is roughly ~56% awareness of KosmicKrisp among Vulkan developers, with roughly one‑third considering or already adopting it, viewing it as the emerging native Vulkan path on Apple platforms.^[1]
