Despite the fact that the Series episodes are not currently working on the Steam Deck, it's still an absolutely incredible game to play on the Steam Deck
You can check out this playlist for Quantum Break Episodes so that you can watch the relevant episode for the choice you make in-game when you reach a junction point or the usual end-of-chapter episode.
Our recommended settings are to set the game to Medium, turn off the Upscaling, turn off v-sync, set the in-game FPS Cap to 30 on, and turn the film grain off.
