Blender is in the process to migrate to the Vulkan GL API. This is a long running and ongoing project mostly done by Clement. The branch is tmp-vulkan and requires to install the vulkan SDK.

The vulkan SDK can be downloaded and installed from https://www.lunarg.com/vulkan-sdk/

On popos20.10 I used the same commands as for Ubuntu 20.04:

wget -qO - https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-1.2.176-focal.list https://packages.lunarg.com/vulkan/1.2.176/lunarg-vulkan-1.2.176-focal.list
sudo apt update
sudo apt install vulkan-sdk

You need to compile blender with the WITH_VULKAN and start blender with --gpu-backend=vulkan.

Currently blender will crash during startup.

Changes to shaders

The plan is to implement VK shaders and convert back to OpenGL shaders. Keeping track of the shaders changes. So we might be able to create a converter.
