Wii U:
The Wii U version consistently falls 6-10fps behind the 360 and PS3 releases, resulting in a jerky, often uneven update and a profound, unsatisfying reduction in controller response. Combined with the GamePad's twitchy analogue sticks, the low frame-rate makes frantically running across rooftops and chasing down targets a frustrating affair, the net result being that we'd often have to repeat some missions multiple times - something that wasn't much of a problem on 360, and with no issues at all when playing at 60fps on the PC version of the game.
Those hoping for the Wii U version to slip somewhere in between the PS3/360 and PS4/XO experience are in for a disappointment though. Ubisoft has created a two-tier product and the Nintendo version is very definitely pegged at the lower level. Native 720p resolution is standard here, and the same in-house post-process anti-aliasing solution is also in effect, delivering similar results to Xbox 360 and PS3. In fact, the only points of difference revolve around slightly reduced texture filtering in some scenes, and a cooler overall colour balance that doesn't quite covey the warm glow of the tropical sun quite as well as the other platforms. Both of these things are small nitpicks though, not harming the overall presentation in any meaningful way.
PS4/XB1:
Thankfully, the performance situation is far more positive when sampling both next generation consoles. While we aren't looking at the 60fps gold standard favoured by enthusiast PC gamers, Black Flag manages to stick closely to a solid 30fps across both formats. In fact, on the PS4 we never felt or noticed anything other than a locked 30fps update at all during our four hours or so of capturing - an impressive feat considering the boost to 1080p rendering. The Xbox One version mostly achieves the same solid 30fps performance at 900p, but there are times when the frame-rate is noticeably compromised, resulting in uneven motion and even the odd torn frame (too few in number to be noticeable).
Illuminating.
