Wii U GamePad display latency is less than many HDTVs

[wraggster]

The Wii U can wirelessly stream data to the touchscreen GamePad controller with just a 1/60th of a second latency.That's according to Rayman creator Michel Ancel, who is developing 2D platformer Rayaman Legends for the console.Such a small amount of lag logically means that a game running in 60fps will lag by just one frame per second. It is a "crazy" achievement, Ancel said."It's crazy because the game is running in full HD [on the television], 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," Ancel told Nintendo Power magazine (via Nintendo Everything (http://nintendoeverything.com/101946/ubisoft-wii-u-gamepad-tech-more-advanced-than-people-may-think-crazy-response-time-low-latency/)). "It's almost instant. That's why it responds so well. So it can be used as a real game-design thing.""This is where Nintendo is really out in front of things," he continued. "The technology inside the controller is quite a bit more advanced than what people might think. It's really responsive. The response time is crazy, in fact, and I think the competitors will need some time to [get their solutions] this responsive."Digital Foundry previously investigated the Wii U GamePad's latency (http://www.eurogamer.net/articles/digitalfoundry-hands-on-with-wii-u) and found it (while wired to the console at a demonstration event) to be seven frames faster than the attached HDTV."Most HDTVs come with a lot of lag as standard," DF chief Richard Leadbetter explained. "Seven frames is absolutely obscene, three or four is more common."Cheap PC monitors are pretty decent these days: they lag by one or two frames, but HDTVs are still using a lot of post-processing technologies, meaning lag is greater."Digital Foundry will be validating these claims once and for all in a detailed hardware review around the console's launch.
