and this time i'm not even dual booting.

I'm so close to doing the same thing. We're at the point where proton compatibility is good enough that most of the games in my library work. And even if a game truly doesn't work on Linux at all, I just talk myself out of buying it anyway.

I think I pretty much only boot up Windows once every few weeks to keep it updated.

Well, sure, proton is great, but I wish HW support was better more than I like proton.

Proton?

Valve puming money in the Steamdeck is paying off for everybody gaming on Linux.

It's a double-edged sword though. It means there's no point in developing native Linux games, because it'll run through Proton anyway. Keeping Windows the default gaming platform still, and making Steam the only way to acquire games if you wanna play on Linux. You CAN add non-steam games to Steam, but they're not guaranteed to work. I don't know if you can also run Proton without Steam because I've never needed to try, but that would be a hassle for your average user.
