Hello,
This question might look dumb but I use some details in Unreal that need directx12, vulkan or metal to work.
So I would like to know how to run unreal with dx12 by default on windows and Vulkan by default on linux (or disable dx10, dx11, and opengl3) using ini files or any other config file, not using -dx12 or -vulkan in the commandline.
I also would like to know how to keep this setting in the packaged game.
