The Xbox One version dips to 52fps in places, which is just fine if you don't mind a little compromise.
Given parity is essentially achieved everywhere else, has the touted Xbox One's resolution boost changed anything in performance testing? With both running at a full 1080p, we see a clear margin when running the New Tristram Gates, during the Skeleton King boss fight, and during packed skirmishes on the South Highlands plains. It reaches as low as 52fps on Xbox One, whereas with the rendering glitch now fully attended to on PS4, Sony's hardware never drops a frame in these areas.
In terms of frame-rate metrics, the Xbox One does show flickers of strain in meeting its recent 1080p upgrade - something never elicited by the PS4, which holds at 60fps in likewise tests. These drops, as infrequent as they are, make it harder to call the Xbox One release a purely locked 60fps experience in pragmatic terms, but it's clearly a solid performer.Digital Foundry
