Only 13% of my Steam library is verified. That's still plenty of games, but it's a lot more limited than "all games on Steam." More than half of the top 20 games on Twitch are unplayable or run terribly on Linux.

It opens some doors if you're willing to accept "playable" games. That's another 14% of my library. The vast majority are a crapshoot for me on the Deck. Most of the issues revolve around text illegibility and clunky controls.
