In order to stream games @ 4K Ultra HD @ 60 FPS, your gaming PC must meet the following minimum requirements:
GPU: Maxwell or Pascal based GeForce® GTX™ GPU 970 or higher GPU
CPU: Intel Core i5
Network: Wired ethernet from SHIELD TV to your router
Due to the high graphics demands of streaming 4K@60FPS, we strongly recommend the GeForce GTX 1080.
Lower end GPUs may GameStream at 4K@60FPS, but with reduced quality settings.
