They are. I have about the same success rate with Proton and WINE(via Heroic Launcher) as to when I still duel booted Windows. If you’re talking about games with rootkit anticheats, I never played those in Windows anyway.
I just use Mint. Just think of Proton as a feature of Steam. I just pick a game from my Steam library and select Force Compatibility mode on and install. Heroic Launcher (for GoG and some other things) is a few more steps, but I didn’t need a guide to figure it out. Heroic lets you choose either Proton or WINE, so I installed Steam first to minimize confusion.
Oh, and another nice feature of Heroic is that it will grab the Linux binary if it’s available somewhere even if that binary isn’t available on GoG. I was surprised that it grabbed the native client for Factorio instead of the windows version that’s on GoG.
