SteamOS 3.8.6 Beta is now available. One of the most interesting changes is the addition of preliminary HDMI VRR support for devices with native HDMI output.
While it may seem like a small changelog entry, it is a good step forward for SteamOS and Linux gaming, Until now, HDMI VRR support on Linux has been more limited than on DisplayPort.
Valve describes the feature as “preliminary,” so limitations may remain.
Other fixes:
>Fixes for Remote Play video freezing issues
>Improvements to VRR frame pacing
>Expanded support for additional handheld gaming devices
>Various stability, performance, and security improvements
