You can add any exe to steam library and set there to hae proton to run it. The hard ones are those that have a setup.exe, there you have to change the path to exe that is to be executed after you have run the setup exe using steam. The correct exe can be found in the corresponding c drive hidden deep in your home dotfiles.

Thanks for the tip.

I agree that games for windows are more easy to run on windows. Only fair comparison is, comparing it how windows handle running Linux games/software. One can say, yea, there is WSL. But you can do exactly the same on Linux using a windows VM and RDP to draw the program window directly into a window in your display manager

I don't really care about what is fair. I care how well the OS can do what I want it to do. I have never seen a Game that run on Linux but not on Windows, so this is irrelevant to me. Playing Windows games is one of my use-cases. If windows is better at it, I don't really care why.
