A lot of people were upset when Ubisoft announced that Assassin's Creed: Unity would have graphical parity with the same resolution and fram rate on both Playstation 4 and Xbox One. Now the game has been out for two days in the US and Digital Foundry has compared the game between the two consoles to see if Ubisoft kept their promise.
And the result might come as a surprise for some gamers, since Assassin's Creed: Unity turned out to run smoother for Xbox One despite the same graphical detail and a 900p resolution to both consoles. It's especially really crowded scenes that makes the Playstation 4 stutter and takes a nose dive to around 20 frames per second, with Xbox One maintaining at least 25.
Digital Foundry says they don't know why there is such a difference, but does give a few attempts to explain it while waiting on the full analysis - which will include PC - in a few days:
"We know that the Microsoft hardware has more CPU time available, and that animation and AI tend to stress processor hardware heavily. The sheer volume of objects on-screen means that the CPU is working overtime in order to prepare the draw-call data for the graphics hardware. There's also the possibility that the Microsoft compiler may be producing more efficient code than its Sony equivalent"
