This will require 2 PCs "your PC specs will vary with your experience"
- client will be the PC that plays games remotely.
- server will be the PC that games are installed on.
- Head over to Steam.
- Create a Steam account it's free.
- Download, install, sign into Steam's desktop application here on both PCs.
- Download/ install any game from Steam to the PC you'd like to use as the server I recommend a free game for this to test your setup.
- Then go to library on the client PC, select the game you just downloaded on your server PC and click stream.
