Steam's Remote Play feature that allows playing Steam games on phones / tablets / TVs / other PCs while streamed from your main gaming system now is able to handle AV1 video streaming.

Today's Steam Beta update has added AV1 video streaming support for Remote Play as one of the interesting changes in this rather sizable update. Today's Steam Beta release notes mention:

Remote Play

- Added support for AV1 video streaming on high end systems.

Details beyond the "high end systems" requirement weren't immediately available but newer AMD / NVIDIA / Intel graphics cards do support accelerated AV1.

This big beta update also updates its bundled Chromium build, adds support for recording GPU-accelerated H.265/HEVC content as part of game recording, support for recording up to 4K when using H.265, a new "--disable-screensaver-inhibit" command-line option for the Steam Linux client, drops support for macOS 10.13/10.14, removes Windows 7 / Windows 8 support, and other changes. Plus a few Linux-specific fixes, including some crash fixes.
