Vulkan or DirectX on Linux?
(slrpnk.net)
I use an AMD card, playing on Bazzite. How and when, do i know when its best to use Vulkan or Directx on linux?
OpenGL is a bit like Vulkan, but discontinued since... 2014, with a single update since then. It was actually stopped because Vulkan seemed better, and both API's were maintained by the same organisation.
In general it's more likely to work on older devices, but would be less performant than Vulkan.
So if a game has OpenGL and DirextX as options such as TF2), it's generally better to pick DirectX?
If you have an Nvidia GPU definitely pick DirectX. On AMD it's more of a tossup, depends on the game and the features in question but generally it won't need to translate OpenGL, so it has higher maximum performance potential.
