Assassin's Creed Unity framerate is closer to 30fps on Xbox One than it is on PS4

Assassin's Creed Unity is not gaining any support when it comes to its technical performance on both PS4 and Xbox One. Digital Foundry has done an early analysis of both versions and come to a shocking surprise yet again.

Unity provides identical image quality on both systems and renders at the same resolution of 900p. However, given the PS4's advantage in GPU memory, one would expect this version to have a leg-up in some way over the Xbox One version.

This is not the case, according to an early analysis of both version by Digital Foundry.

"Assassin's Creed Unity falls short of the performance standard set by last year's Black Flag, featuring considerably more variable frame-rates under load on both consoles. Given the immense graphical upgrade on offer, this isn't so surprising, but what comes as a bit of a shock is that the Xbox One version frequently out-performs the PS4 game in more detail-rich areas, such as locations littered with NPCs in the packed Parisian streets.

"The opening clip in our video below perfectly demonstrates the difference between the two consoles. Wading through dozens of NPCs in a crowded square, performance drops down to around 20fps for a sustained duration on the PS4 while the Xbox One achieves a 5fps lead. In a later gameplay test traversing the rooftops, we see frame rates regularly fluctuate between 25-30fps across both consoles, but here the Xbox One game sticks more closely to the upper end of that spectrum than its Sony equivalent."

Both platforms deliver the same performance when it comes to in-door scenes. Cutscenes are where the PS4 version shines, as the Xbox One fails to achieve the 30fps target.

As the site points out, the performance disparity between both systems, especially where that disparity is manifested, is really bizarre. Which perhaps could be attributed to the game simply needing more time in the oven.

There is also a video below showing both versions side-by-side.

Digital Foundry will provide a more in-depth look at both systems, along with PC, when they've spent more times with the game.
