• Install the latest GeForce display driver available at http://www.geforce.com/drivers.  This will automatically install GeForce Experience software.
• Launch GeForce Experience.
• Log in to GeForce Experience with your NVIDIA account.  This is the same account used in NVIDIA Games app on your SHIELD.  If you have not created an NVIDIA you can create one here.
• On the Settings > SHIELD page, enable the "GAMESTREAM" switch.

• Your PC is now configured for GameStream.

NOTE: Even if a game has been downloaded onto your PC, often times the game must be run once to compete the installation process.  We recommend running newly installed games once on your PC before GameStreaming.
