I’ve considered it, although it’d be a situation where it would probably just be the game code without assets (sounds, textures, etc.), since those are under different licenses. Also, it’s not really a “living” game like most FOSS games - once it’s released it will pretty much be in its final form. So if I make the code public it’ll mostly just be for reference.
Yeah that’s big area that’s shaky with proton. Fortunately a few games have been adding support (halo MCC recently did). And for me, I typically only play singleplayer games - the most modern multiplayer game I play is titanfall 2 which works great on Linux.
But for someone who does play those games, I can see how the lack of them can be a huge obstacle.
I switched last year and kind of was in a similar spot to you - I had tried to switch in the past but something didn’t work so I went back to windows. But that last attempt has stuck. So I’d just do it. Proton is in an amazing state, old games and even most new singleplayer games will work - some modern multiplayer games with anticheat even work. I’d just check your library on protondb (you can sign in to see your library), see what doesn’t work, if you care about it, or if there are workarounds.
What I also did is make a list of stuff that doesn’t work and then find alternatives or workarounds. If some games don’t work, you can hold off on switching, check protondb occasionally and see if something changes. But if it’s all good, I’d just make the jump.
The steam deck uses arch, not Manjaro (although Manjaro is based off arch). But ultimately it doesn’t matter too much what distro you use for gaming.
Arch is a weird recommendation for beginners, even with the better install process. The aur is nice but isn’t necessary imo. Fedora works fine, or I’d recommend mint for something a bit more “stable.” I’ve been using both for a while with minimal issues.
I guess it depends on where your games are. I have a few games on epic and gog, and for that Heroic works great. So personally, I just use that and steam. The nice thing about heroic is that it lets me select steam’s installed proton versions, so I don’t have to install proton multiple times.
At the end of the day though, if you can launch the games you want to play, stick with what you got.
Probably not, but so far they haven’t gone after any recompilations.
