Eurogamer recently went hands-on with Wii U. During their trial, the Wii U GamePad’s image did not lag behind the television screen and, as a matter of fact, Wii U’s controller rendered faster than the TV. Eurogamer claims that the Wii U GamePad’s connectivity with the TV is
significantly better than the PlayStation Portable’s “heavily buffered Remote Play feature.”

“Latency also factors into the equation when using any wireless device, and memories of the PSP’s heavily buffered Remote Play feature have us hoping for a significantly reduced delay between the higher and lower screens. Fortunately, we’re pleased to find that latency here is impossible to pick out without some exacting method of measure. In testing the difference, we find results that completely subvert our expectations here; in instances where gameplay is mirrored between the two, the GamePad screen actually renders the image 116ms before the 50-inch LG screen does.”
