If youve been busy shaving seconds off lap times in the stunning Mario Kart 8, youll be pleased to know that Nintendo has shaved some seconds off the time it takes to boot up the game. A new Wii U system update, version 5.00, comes with a quick start menu that displays recently played games on the controller screen as soon as you power the system on, letting you load them straight away rather than wait for the full operating system to start up. Version 5.00 also includes the facility to automatically download and install system updates, and Nintendo can send a new kind of notification to the GamePad controller even when the console is switched off. The Wii Us laggy system-level performance has been a major criticism of the console since launch. The Verge noted it in our initial review, and Nintendo has since promised a series of updates to speed the OS up.
