What codec is used to transfer video to SteamLink?
It must be quite fast to encode image at realtime (plus, game engine requires lots if resources too) , and it probably should produce quite low bitrate to not consume whole bandwidth of home network (100Mbps, but home grade devices usually not reach full paper potential nicely).

I reckon the difference is that on Windows the video encoding is using the hardware encoder on my RX480, while on Linux it's not. In order to encode frames quickly enough with the software encoder and still have CPU cycles left to run the game, the encoder quality is sacrificed.

Also most traffic on home network is to/from Internet, so unless the guy has 50+Mbit internet is mostly free.
People that have NAS and other stuff (and use them seriously) have already invested the whopping 30$ to get a gigabit 8-port switch to upgrade their home network to the 21st century speeds.

The Marvell Armada SoC inside the Steam Link is a decent mediacenter system so it has hardware decode acceleration for more or less anything apart from H.265 https://www.anandtech.com/show/5296/...-armada-1500/2
So it's not using h.265 for sure.Last edited by starshipeleven; 31 October 2017, 10:01 AM.

Yeah, it's H.264. See https://github.com/ValveSoftware/ste...ux/issues/4890 for some example log messages identifying the encode method on both Windows and Linux.

Steam Link receives streams in the LAN and has a 100Mbit port itself, I don't think a modem is relevant for it as it does not stream over the internet (the Steam Link anyway).
