====== Ubuntu - GPU - AMDVLK ======

**AMDVLK** is the AMD official open-source Vulkan driver for Linux systems.

  * AMDVLK is derived from the same sources as their Windows/Linux proprietary driver but built against the open-source AMDGPU LLVM shader compiler rather than AMDs proprietary shader compiler.

AMDVLK comes with something AMD calls "AMD switchable graphics layer" in the form of a implicit layer library and configuration file in **/etc/vulkan/implicit_layer.d/amd_icd64.json**.

  * This lets you choose what Vulkan driver to use by setting **AMD_VULKAN_ICD** to **AMDVLK** or **RADV** if you choose to install the AMDVLK driver side-by-side with the Mesa RADV Vulkan driver.
