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
