WSL 2 in early development stage as Vulkan over d3d12 in Mesa 22.1. RustiCL is available at 22.3 with official OpenCL 3.0 Conformance for Intel XE Graphics. Performance is equal and better to AMD ROCm with AMD 6700 XT Card. A main development target of Mesa 23.0 was ray tracing for Vulkan. Microsoft develops dozen driver for Vulkan in WSL. Vulkan 1.2+ will be available in Mesa 23.1. Table of Rendering APIs Vulkan The Khronos Group officially announced Vulkan API in March 2015, and officially released Vulkan 1.0 on 16 February 2016. Vulkan breaks compatibility with OpenGL and completely abandons its monolithic state machine concept. The developers of Gallium3D called Vulkan to be something along the lines of Gallium3D 2.0 – Gallium3D separates the code that implements the OpenGL state machine from the code that is specific to the hardware. Version 1.3 is immediately available with Mesa 22.0. Hardware with support of OpenGL ES 3.1 should run at Vulkan Level 1.3 and before. As Gallium3D ingests TGSI, Vulkan ingests SPIR-V (Standard Portable Intermediate Representation version "V" as in "Vulkan"). Intel released their implementation of a Vulkan driver for their hardware the day the specification was officially released, but it was only mainlined in April and so became part of Mesa 12.0, released in July 2016. While already the i965 driver wasn't written according to the Gallium3D specifications, for the Vulkan driver it makes even less sense to flange it on top of Gallium3D. Similarly there is no technical reason to flange it with NIR, but yet Intel's employees implemented their Vulkan driver that way. It is to be expected that AMD's own proprietary Vulkan driver, which was released in March, and was announced to be released as free and open-source software in the future and be mainlined into Mesa, also abandons Gallium3D. RADV is a free project for AMD and is available since version 13. Conformance with Khronos-Test came in version 17.3. Actual is Full support of Vulkan 1.0 and 1.1 since Mesa 18.1. Nvidia released their proprietary GeForce driver with Vulkan support at launch day and Imagination Technologies (PowerVR), Qualcomm (Adreno) and ARM (Mali) have done the same or at least announced proprietary Vulkan drivers for Android and other operating systems. But when and whether additional free and open-source Vulkan implementations for these GPUs will show up, remains to be seen. Mesa Software Driver VIRGL starts Vulkan Development in
