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 7Mbps upload and download speed recommended. Streaming will also require a GTX 650 or up on the host PC (laptop support is coming later), and it's only compatible with the Google Chrome browser via a plug-in.

In addition to GameStream co-op, Nvidia is adding a new UI for its ShadowPlay DVR capture suite, which is also part of GeForce Experience. A new overlay gives users instant access to ShadowPlay, allowing them to start and stop recording, activate instant play recording (which continuously captures the last few minutes of video), and perform quick edits and upload directly to YouTube. Twitch streaming is also built in along with recording options for microphones and webcams.

Finally for all the MOBA players out there, Nvidia has added a new optimisation mode to GeForce Experience specifically for the genre. Instead of optimising for visual fidelity, GeForce Experience will aim to boost your frame rate instead (up to 120 FPS), which Nvidia says will improve the responsiveness of the game for competitive play.
