I use Grapejuice. It's a simple flatpak that I can install and it just works. You just need to go into its settings and choose between Vulkan, D3D11 or something else if the performance isn't good.
EDIT: just found out about Vinegar, I'll try it later. Apparently it's better than Grapejuice
EDIT 2: the game doesn't launch with it even after following the troubleshooting instructions, so if this doesn't work for you use Grapejuice
I'm starting to think people on here don't even read the articles and just get paranoid about any new thing they add to operating systems
