It’s hardware Vulkan graphics only. A friend I played the multiplayer mod with doesn’t have Vulkan. I myself for a while played on a computer that doesn’t have Vulkan (well, technically does but most of the things I’ve tried to run just black screened because of missing functions).

Speaking of the multiplayer mod, it’s no simple text file shit. I built it by downloading dotnet from marcoshaft. I wonder how mods like these (in general, not this specific one) are claimed to be compatible, I guess they rewrote Unity builtins or something. In the modern day and age, sounds like something that would be LLM assisted… We will see if it sucks I guess.
