NVIDIA officially supports GameStream for over 200 games, but GeForce Experience allows users to manually add and stream nearly any game.
Open GeForce Experience and navigate to the Settings > SHIELD settings.
Under the Games and Apps window, click "ADD" and browse to the location of your game's launcher.
(Optional) If you would
like to edit the display and add custom box art to your manually added
game, click "EDIT."
Here you can set the display name by selecting the
icon to edit the name and box art of the applications in your list.
Once you have added applications into the list, they will appear on your SHIELD TV as GameStream games and can be launched just like any other app. Note that NVIDIA does not configure optimal settings for manually added games, so you may need to adjust in-game settings manually for the best experience.
TIP
You can even use this feature to stream your entire PC desktop. To do
so, add a shortcut to Windows’ Remote Desktop Connection app (c:\windows\system32\mstsc.exe)
in GeForce Experience, then select the newly added Remote Desktop tile
from SHIELD ’s "PC GAMES" tab. From here, you have access to
your entire desktop.
