Buy a Steam Link and a raspberry pi, and two usb eth adapters, create a ZeroTier network and configure the pi (openwrt) to get internet from one of the adapters and share both the internet connection and the zerotier connection over the second adapter. Configure the zerotier network on your computer and set ul Steam In-House streaming. Then you can take the pi and steam link anywhere, plug a mouse, keyboard and screen, and use your computer. I get 60fps at 1080p and no noticeable input lag over the internet (work to home).

If you use a nvidia card enable "force composition pipeline". There is also a Steam Link app for Android, and ZT client as well, works great.
