The GeForce Experience client received an upgrade, announced at the CES 2017 Nvidia Keynote from the Venetian hotel in Las Vegas. CEO Jen-Hsun Huang took the stage and announced this upgrade, which would allow players to quickly stream to Facebook Live’s streaming service.
The upgrade, once installed, only needs the player to press Alt+Z, and supports webcam and micrpphone usage. Screenshots and videos can also be shared directly to your Facebook timeline with Alt+F1 allowing for screenshot capture and the recorded video being uploaded with the Alt+F9 command.
Nvidia has provided a walkthrough, which can be accessed here.
