For cloud gaming I have used Stadia, GeForce Now, Xbox Cloud Gaming, and now Boosteroid.

It has been great. No need to worry about installation and storage space. Simply click and launch the game.

You do need to have reliable internet, preferably wired LAN or a fast wifi network.

For self-hosted streaming I use Steam Link, Sunshine or Parsec. Mostly Sunshine these days because of the streaming quality.

I mostly play single player games and I don’t really notice any lag.
