Nvidia GeForce Experience update lets you share games, play co-op

Nvidia is adding a new feature to its GeForce Experience software that will allow users to stream a game to another user's PC over the Internet, and play cooperatively with a just a single copy. The feature, dubbed GameStream co-op, is launching as part of a beta release of GeForce Experience in the coming weeks.

GameStream co-op, which is similar to Sony's Share Play feature on PlayStation 4, offers users three different modes. The first allows a friend to observe the game; the second mirrors the controls of the host PC on the guest PC, allowing the user to take over control of the game; and the third enables co-op play. While the observation and mirror modes will require no extra work from developers to implement, some may be required for co-op play.

GameStream co-op uses the same technology behind Nvidia's GameStream service, which allows users to stream a game over a local network from their PC to another device like a Shield tablet. However, unlike the 1080p support of GameStream, GameStream co-op will initially only support 720p streaming at 60 FPS using h.264 encoding, with a minimum 6Mbps upload speed recommended. Streaming will also only be compatible with the Google Chrome browser via a plug-in.
