As documented by a few different channels on YouTube, Borderlands 4 on Steam Deck is technically playable, but looks extremely rough, features plenty of input lag, runs poorly at its default settings, and doesn’t at all seem worthy of Steam’s Verified badge. That’s supposed to signal to players that a game will be a great experience with no tweaking needed on the aging portable PC. But that’s simply not true of Borderlands 4 on Steam Deck.
