CS:GO is far from a "recent" game. It still gets regularly updates sure, but it's nearly a decade old and the engine hasn't evolved in that time in a way that would make it comparable to a current-gen game.
Sure, but that's not what was up for debate in the comment chain you were responding to. That was specifically about how well it handles "recent" games. Not how well it handles old but still popular games. WoW also runs great under Wine for example afaik.
I'm not diminishing the value of games like that running well under Wine, I think it's great. But it's not the same as "recent" games running well.
As one of the GPs points out anti-cheat is unfortunately another big hurdle. CS:GO works great because VAC runs in user-mode and Valve go out of their way to specifically detect Wine and adjust behavior as appropriate (I reverse engineered it extensively some years ago). I think EAC has a native Linux client, but many of the big names are still unplayable.
If you try to play Valorant, Apex, Siege, Warzone, PUBG, etc. my understanding is they'll barely even launch, let alone allow you to join a multiplayer match.
I think "it does not play most recent games" is untrue without qualification.
