Is Steam Big Picture an update or simply a compatibility tweak? Does it add new functions to the client, or just patches some hardware support?
Steam Big Picture is a mode of Steam that enables you to control and play games as if it were on a media center. It's recommended to be used on big TVs because it's more practical. It has the same functions as the normal Steam client, only that the navigation is increased in terms of functionality, and besides that it looks nicer.
