About a month ago, we've reported NVIDIA's announcement of a major GeForce Experience update in September that would have enabled GameStream Co-op, allowing similar features to PlayStation 4's Share Play.
The GeForce Experience Early Access Share beta is available now; you won't get any update on your client, which is probably because NVIDIA wants only dedicated users to try this at the moment.
The small download (37,9 mb) will update your GeForce Experience software to this beta version. A new "Share" tab is added under Preferences, and this is where you control every option of the sharing experience.
Here's a list of the new features as advertised by NVIDIA.
In addition, gamers can now save and upload directly to YouTube from within the game through the new Share overlay by selecting the Upload option. Trim and title the video and send it right to YouTube. There is even a Gallery option to view and upload recently captured video.
