As seen in the above video, Assassin’s Creed Black Flag Resynced often dips below its target frame rate of 30 fps on the Steam Deck using the lowest graphical settings. That said, it is able to run at or close to the target for the most part. As such, we consider the game barely playable on Valve’s handheld device.
