Nvidia is preparing a GeForce Experience beta that will debut a fun new feature, as well as functionality tweaks and enhancements. This early access beta is coming in September and the headlining new feature will allow you to play co-op with friends who don't own either the game or have any Nvidia GPU in their PCs.
This feature allows you to stream your game over the internet and co-operatively play with a friend "just as if your friend was sitting in the chair next to you," says Nvidia. Using GameStream Co-op mode you can play in co-op mode with a friend for fun or to get help on a touch level, or simply live stream a 1:1 to the friend. Nvidia's list of requirements for host PC and Guest PC are listed below. It's nice to see that the guest isn't required to have an Nvidia GPU.
The GameStream Co-op mode was demoed by Nvidia in the game Trine 3. In the video above, you can see a friend takes over play at one point, later on the friend is invited to play alongside, as Trine 3 supports this style of gameplay.

Nvidia's ShadowPlay, used to "record and share your greatest gaming moments" will be enhanced in the beta to provide easier access to its controls and easier sharing to YouTube.
For easier access, in-game users of the beta will be able to make use of a quick-access recording and Twitch broadcasting overlay. In addition gamers will be able to save video and upload directly to YouTube from the share overlay. You can quickly trim and title the video before you upload it.
As mentioned in the intro, these new features will be able to test out starting from next month.
