Information about running games on Vulkan, on Linux systems

There are a few ways of playing a game under vulkan:

Native: The game/engine natively supports vulkan
Native (dxvk): The game/engine natively runs on Linux, but uses a translation layer to run dxvk (e.g Vulkan support on Source games)
Proton: The game is not native, but uses directx on windows, and therefore, dxvk on linux trough proton
Zink: The game does not support vulkan/directx and uses opengl, is possible to use Zink (not recommended)
