Can I stream games I already own on GeForce NOW?
No. Games need to be loaded on our GeForce NOW servers to enable us to stream them to your SHIELD Portable . Our goal is to provide the best catalog of games we can offer from the thousands of PC games available. Members can also purchase newly released games from the GeForce NOW store. Most store purchases also include a digital key that lets you download and play the game on your own PC. GeForce NOW will display the message: "digital download key included with purchase" prior to checkout when a publisher has included this option.
