ProtonDB is older then the steamdeck my dude, protonb was released alongside proton, which released on 2018, while the deck is from 2022.
In any case, I agree with you, it’s a very reliable source of game support. Mainly because it’s user reported haha.
I wanna downvote because you called metal shitty growls and screams, but I’m no transphobe so you get a comment >:(
Metal people are the most chill people always, have you seen Serj outside of musical videos? He’s almost a hippie.
