Not gonna lie, I bought this mainly for gamestream, then as streaming device second. Gamestream is a headache to setup but once you have 1) really good gaming rig, 2) fix whatever bugs there are, this is capable of gamestreaming 4k60 even with a very fast 5ghz wifi (I have Ac3150 beamforming router with AC1900 beamforming capable card on the rig). So far I've played Rocket League, a few Assassin's Creed games, and tried Battlefield V Campaign for the lol. Stutters only come if someone walks through the hallway between the router and the office where the Desktop is situated. Aside from that, the 4k60 stream is excellent and the wireless xbox360 gamepad input lag is bearable to singleplayer games. Don't bother trying on games that require no input lag at all. The AI Upscale is a pleasant surprise and Netflix standard streaming looks like a legit 4k stream. Compared to when I stream directly from my Smart TV. On the other hand, my 4k HDR streams from Disney Channel is working flawlessly with my HDR capable TV. On another note, my Dolby digital sound is going through the the shield, then to TV then to TV's HDMI ARC connected to a samsung Dolby 5.1 Soundbar + wireless soundwoofer & rear speakers. So I can attest that Dolby passthrough works. Not sure about Dolby atmos though. It is also good for running android games or if you subscribe, Nvidia's GeForce Now. Also, the price is pretty high up there so the only worth it specs from this device is the gamestream and the AI upscale. If you can't justify that cost, you should try looking at other cheaper streaming device then. Side note, turn on HDMI-CEC on the shield and your tv. This will allow you to turn on the Shield, the TV and the Sound bar all at the same time with just the Shield's remote. Also, turn on the HDMI-CEC volume control (alongside in the TV settings). I only need the Shield's remote through this setting to turn on, and even mute and adjust volume.
