Ubuntu - GPU - AMDVLK - Select the AMDVLK Vulkan Driver

Select the AMDVLK Vulkan Driver

export AMD_VULKAN_ICD=AMDVLK

NOTE: AMDVLK is the default, but may cause issues with Steam and other applications.

RADV is often much better, faster and more up to date!

Select the Mesa RADV Vulkan Driver

export AMD_VULKAN_ICD=RADV

Reenable the ICD based loading approach

Alternatively to the above.

export DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1

NOTE: When DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1, you can choose your preferred Vulkan driver by setting the environment variable VK_ICD_FILENAMES.

For example, running Steam with the RADV driver is done by:

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json steam

To avoid crashes with 32-bit games, it is possible to assign the 32-bit variant and the 64-bit variant to the environment variable.
