Besides the GeForce GTX 950, NVIDIA also announced upcoming feature updates for its GeForce Experience software. You can expect these as part of a new beta release in the coming weeks.
First up, the tool will includes a feature that gives you an in-game overlay to record videos and upload them to YouTube or broadcast them to Twitch.
Another and perhaps more exciting new feature is GameStream Co-op, this lets you share games with friends in all sorts of ways. It is a bit similar to Sony's Share Play on the PS4, it allows you to show off games to friends and by transferring the control to the guest PC they can test the game or help you out in a difficult level.
These are the observe and mirror modes, there will also be a co-op play mode that lets you and a friend play cooperatively, just as if you were sitting next to each other, but ARS Technica writes this may require some coding work from the game developers.
GameStream co-op uses the same technology as NVIDIA's GameStream service but it's limited to a 720p resolution and 30fps. The host PC will need a GeForce GTX 650 card or better and for smooth play you'll need an Internet connection with download and upload connectivity of at least 7Mbps. Guest PCs will need to install a plug-in, which at the moment is only compatible with Google Chrome. Additionally, we hear gameplay will be limited to one hour to prevent unlimited sharing.
