In either of these games, gameplay projected to the HDTV is typically mirrored to the smaller screen, and the high level of clarity does heavily suggest that the controller is being sent a separate framebuffer to suit its native resolution, as opposed to having the HDTV's 1280x720 output downscaled. Such additional scaling would result in a degree of blurriness, which we do find to be somewhat true of games like New Super Mario Bros. U. In this case, we notice the lower display leaves Mario looking fuzzier than he perhaps should - and certainly not as crisply rendered compared to characters in Rayman Legends. Of course, this is based on a very early demo, and quality may be subject to change.
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.
