GeForce Experience is a software made by Nvidia that optimizes PC games's graphical settings to match the machine they run on. It also integrates Nvidia ShadowPlay, an excellent recording software appreciated for its minimal impact on performance, and a streaming function towards Nvidia Shield.
Now it's going to take the next step and provide more features in the form of GeForce Experience Share.
You can summon an overlay by hitting Alt+Z, and it's accessible in-game and even outside the game.
Instant Replay saves your last 5 to 20 minutes of gameplay, or you can use the Record function to start and end a recording whenever you please.
The recording usually uses ShadowPlay, that records at almost no performance cost up to 4K video quality and at 60 FPS.
Once you recorded your clip, you can review it in the Gallery and upload it straight to YouTube via the overlay itself, without the need of exiting the game.
There's also a quick editing function if you wanna cut parts of the video before uploading it.
You can set the parameters of the recording quality of course, such as length, framerate, or streaming quality.
Via the overlay, you can also start a Twitch stream, adding your voice and camera recording if you want, of course.
But the big news is GameStream Co-op.
Basically your friends, through the Internet, can simply watch you play a game, or take control of it to help you out in tough situations, or play with you in co-op supporting games like Trine, FIFA, Mortal Kombat etc.
