Where can I get this application?
I believe it is only available on steam with purchase of the game. This is specifically the vulkan backend for the editor, it also supports D3D11 and 12 and but only the 11 backend semi-works under current proton version, and 12 generates same behavior with patch. I am available and moderately capable to debug it on my end, presently I'm unsure where to look.
