The GamePad is undoubtedly the star of the Wii U show, and Rayman creator Michel Ancel recently spoke highly of the device.
Conceptually simple - two screens, on on a handheld tablet, communication between the console and controller requires a lot of work and fined-tuned setup to get both images and button presses in perfect sync wirelessly.
In the latest issue of Nintendo Power Ancel explained why he feels the GamePad "responds so well" - the lack of any delay between the player inputting and the Wii U itself.
It's crazy because the game is running in full HD
, we are streaming another picture on the GamePad screen, and it's still 60 frames per second. And the latency on the controller is just 1/60 of a second, so it's one frame late. It's crazy, it's so fast. It's almost instant. That's why it responds so well. So it can be used as a real game-design thing.
Rayman Legends will glide exclusively onto Wii U within the launch period, but not from day one.
