I can see that, but I will point out that even on that front I haven’t run into any issues. But here’s a quick run down of what I’ve played and/or proton said is good vs not.
Works: The Finals, Dota, CSGO, deadlock, Arc Raiders, marvel rivals, overwatch 2 (I don’t play this), rocket League (I haven’t tried on Linux but proton says it’s good), dune (haven’t played), world of tanks (haven’t tried but proton says it’s good),
Doesn’t work: Valorant, fortnite, rainbow six siege, warzone, rust (?), pubg, Apex legends, delta force.
Without running the numbers but looking at the stats page of steam, it’s probably safe to say more than 75% or more of all current players would be unaffected by moving to Linux in terms of compatibility. That’s a little unfair because CSGO does like 10 of these games in player count every day.
The non-steam games probably skew this percentage lower but still, it’s not like the multiplayer or competitive multiplayer scene is dry and vacant on Linux.
Ya sorry, I listed two groups without explaining what the groups meant.
