Ubisoft has worked on improving Assassin’s Creed IV’s performance on Wii U
Assassin’s Creed III suffered from some performance issues on all consoles, including Wii U.
In the Wii U version, one issue that was particularly apparent concerns framerate slowdown during crowded battle scenes.
Such problems have been addressed for the next entry in the series, according to Ubisoft Quebec’s Robin Lavallée.
Lavallée told Nintendo Life of the performance in Assassin’s Creed IV: Black Flag:
I’m happy you are asking the question, the team worked really hard during the last month to increase the performances on the Wii U version… and one of those points was the crowded battle scenes. So the quick answer is, yes we have worked to improve this on Black Flag.
…The Wii U architecture poses some technical challenges that we’ve been able to thankfully overcome. It hasn’t been easy, but we’re really proud of the final result on this console.
