Having played Doom, Oblivion, Blue Prince, and Clair Obscur on linux, I can tell you that the tinker steps are unnecessary. I have literally just clicked play and didn't need to think about it. This didn't require a bunch of manual setup to get to that point either; I installed Endeavour and it installed the drivers I needed, then I installed Steam as normal and it was like nothing had changed from my Windows install.
People will post their tinker steps for everything. It's often just to disable the steam overlay, or inject their own overlay, or whatever they think gets them an extra 2 fps. It's linux and people love to configure it their way, but honestly steam/proton handles it automatically 99% of the time.
