Is switching to Linux for gaming worth it yet?

protondb is where people report how each game runs on linux - check your top five there before you wipe anything. dual boot first if you're not sure, you lose nothing that way. and if you're on nvidia, pick a distro that makes the proprietary driver easy rather than doing it by hand.

For a lot of people, yes. Steam's Proton layer runs most single-player Windows games fine now, a big chunk of them with no tweaking at all. The Steam Deck is basically proof of that. The catch is multiplayer games with kernel-level anti-cheat. Some of the big competitive ones just refuse to run on Linux, and no setting fixes it. So before switching, look up the specific games you play the most and check whether they work. If your main game is one of the blocked ones, dual boot or stay put. If not, it's a pretty painless switch these days.
