Amazon Video is the first UHD beneficiary, but also Nvidia GameStream (the feature that lets you stream games from your GeForce-powered PC to your Shield). HBO Got got Cast support, Plex now supports high-end speaker configurations (4.1, 6.1 and 8.1) and the Shield remote got a Pause function (double tap the volume slider).
A handful of new games were added, including The Witcher III: Wild Hunt, The Witness, No Man’s Sky and others. Non-game app additions include NFL, Twitter, Comedy Central and Vimeo. You can also check up on your Nest Cams through the dedicated app.
