Valve continues refining SteamOS with its latest update, addressing long-standing issues while introducing performance enhancements. The SteamOS 3.7.20 version officially integrates the NTsync driver from beta testing, promising potential performance boosts for games using the Proton compatibility layer. This update follows Valve's ongoing efforts to improve the Steam Deck experience since its launch.

The patch fixes several persistent problems including flickering UI elements, low-resolution thumbnails, and controller LED malfunctions. Valve has also improved accessibility features with high contrast mode fixes, enhanced family sharing options, and added notification settings for achievement unlocks. Users can now provide anonymized framerate data to help Steam improve compatibility.

Most notably, the NTsync driver represents a significant technical improvement that could boost gaming performance on Linux systems. While not guaranteed for all titles, this kernel-level support reduces community development burden by providing official implementation. The update also addresses several input-related bugs, particularly for gyro controls and button mapping on various controllers.

Other improvements include better display of high-resolution game capsules in the recent games carousel and enhanced Steam Input options. Users can now apply gyro settings on a per-axis or circular basis, and Button Chord Activator now offers multi-button selection for newer controllers with additional grip buttons.
