Valve has announced that its In-Home streaming service is available to everyone on Steam. The feature, which has been in beta until now, allows Steam users to stream their games from one PC to another on their home network.
Logging into your Steam account on two computers, using the same network, will automatically connect them. Once connected, your primary rig, the remote computer, can stream video games, including graphically demanding ones, to a lower-end PC or laptop. What you can stream is determined by a game’s system requirements but such requirements won’t affect what kind of computer you stream it to.
As of right now, Steam users will not be able to host the stream from Windows XP, Mac OS X, or SteamOS/Linux machines. But the remote PC will stream games to the aforementioned platforms.
Users will also be able to remotely install, launch, and play games from the secondary computer as if they were using the remote PC. In addition, keyboard, mouse, and controller input is sent back to the remote computer.
