Assassin's Creed Syndicate shows genuine improvement here. In Unity, we could see extended periods of gameplay where the 30fps target was nowhere in sight. Its successor shows huge improvement on both platforms, but it's clear that the PlayStation 4 takes pole position. We have two videos below outlining the performance differential, concentrating on engine cut-scenes and gameplay. In the former, GPU load is significantly higher than it is during gameplay, and Xbox One's less capable graphics hardware has more of an issue coping with the load, with sustained drops in performance in some areas, dipping beneath the 30fps threshold while PS4 holds firm. In areas where the Sony console does drop frames, Xbox One lags still further behind.
