SteamOS 3.7.20 Beta Update

There was a brand new, small SteamOS beta update that was released yesterday, but it's still a nice improvement here. The ntsync driver was added to SteamOS, which could see some games possibly perform better on the Deck that match NT Synchronization primitives for better accuracy. It's not going to be a huge increase for every game, but it could help with some.

You can download the updates yourself in the System Settings on the Steam Deck. Make sure your update channel is set to Beta or Preview.

SteamOS 3.7.20 Beta Update Changelog:

General

  • Added ntsync driver

Non-Deck

  • Enabled polkit for the InputPlumber dbus interface and resolved a potential race condition for the InputPlumber interface, addressing CVE-2025-66005 and CVE-2025-14338
