I will agree Proton isn't perfect, but I will also agree that outside of pro-Gamer needs, it is a platforms in and of itself that has a very good selection that I certainly can live with, and certainly seems much more appealing than e.g. gaming on MacOS.
I didn't have to configure a single thing to get excellent and bug-free performance on games like Witcher III and GTA V, and a host of others too.
IT is true that we can enjoy mroe games on Linux then Mac users that upgraded to latest OSX.
It is also true that some games are supported by Valve and they should just work.
But there are more games that don't "just work" then games that do. I would prefer to the community would be more honest about it, like if you want to convince someone to try Linux and you show him that his preferred game is "Platinum" or "Gold" but the reality is different then the Linux community will become even more of a joke.
