Steam adds low-latency Pyrowave codec to Remote Play — new codec offers better game streaming on local networks but costs '5-10 times' more bandwidth

Game streaming over your local area network is cool, but game streaming as typically implemented is basically a hack. It borrows video streaming technology and applies it to interactive games, which isn't actually a great fit, like so many cases of using a tool for a task it wasn't really designed for. Legendary open-source dev Hans-Kristian "TheMaister" Arntzen (known for the libretro framework and Retroarch frontend), decided to tackle this problem by making a video codec called Pyrowave specifically designed for in-home game streaming, and now, that exact codec is implemented in the Steam beta client.

Your LAN has less than 10 milliseconds of latency; less than one millisecond if it's wired. However, in-home game streaming rarely achieves latency anywhere close to that because the process of rendering the game, encoding a video, sending it over the network, and then decoding it (before you can even see the new frame and react) usually takes upwards of tens of milliseconds, meaning …
