Streaming from an Xbox One to a Windows 10 PC will be entirely dependant on the quality of your local network, whether that be via ethernet or WiFi, and the quality of the experience will be largely down to latency. 

The latency and quality of signal when using WiFi is dependant on the environment - that is, quality of walls, other WiFi networks in the same area, etc, so if you're having issues it might be worth re-testing with a wired connection.
