NVIDIA just updated GeForce Experience, adding a neat little feature that allows you to stream your game to a friend’s computer. This allows them to take control of your game, or even play it with you in co-op play, whether they own the game or not.
They also added an overlay that can be brought up in-game to activate various features of the software, such as the game DVR. In order to take advantage of the new co-op features, you’ll need a GTX650 or higher. This is a neat feature, but I wonder how much use it’ll get with PC games.
