How do I get Steam Indie Games to run under Linux or even a Mac? [duplicate]
Solution 1:
Go to the settings of Steam and enable Proton. This will allow you to download every game while on Liunx and launch them via Steam, which takes care of setting up Proton for it. See the official documentation how to start. While this does not guarantee that every game runs flawlessly, I've had some great success running Windows only games with it.
