I was able to get it running great on Windows with an AMD GPU by following this guide EXACTLY: https://vivanewvegas.moddinglinked.com/ Honestly though, this is way too much work to go through just to get the game running and stable, I think just the mandatory parts of that guide took me almost 2 hours to go through. (Maybe that isn't actually very long to spend installing mods? idk I typically never mod games heavily)
