Recently, one of the developers at Crytek was able to get 
Crysis 3 running on 
the Wii U. Despite the fact that the game was not set up to run on the Wii U and the 
fact that it was quickly ported over for experimental purposes, they had the graphically 
demanding game running at 35 FPS in 720p.
  
  That being said, Crytek said that they believe they can get the game running smoothly 
at 1080p on the Wii U. Apparently, the reason for the slow FPS was the fact that they 
had the game running on both the TV and the GamePad. Their development Kit did 
not allow them to turn off streaming to the controller.
