Our initial analysis showed some hefty drops from the target 30fps, but it gets worse. In Xbox One's case, we saw glaring stutters during general play, particularly while drawing weapons or moving through complex cities - an issue not experienced to the same level on PS4. Meanwhile, Sony's machine struggled with heavy alpha effects in battles, though general traversal ran at a smoother rate. However, moving to demanding areas like the Corvega factory, or even shootouts around the Cambridge college area, frame-rates take a nosedive to 20fps and lower.

Alas, Microsoft's machine suffers from a similar nadir in the factory's sewers - in what is presumably a less CPU- or GPU-intensive scenario. At the sight of an empty hallway, we see a 17fps drop on Xbox One, in the middle of each console wavering at around the 20-30fps range. It's yet another sign that the game could use another optimisation parse, and most puzzlingly of all, there's no clear cause for these drops at all. There's a sense that the computational effort going into these scenes isn't matched by the visual return - and again, impact on controller response is a big distraction.
