After a chunk of time in the preview branch, the new SteamOS updates are finally moving into the beta branch, inching closer to a full stable release. SteamOS 3.7.5 Beta features tons of great improvements, including updating the Linux kernel and graphics driver, support for new controllers like the Proteus Byowave, battery level display for Bluetooth devices, and support for frame limiting on VRR displays.

We also got the start of support for ASUS and Lenovo handhelds, as well as starting to support other non-Steam Deck handhelds. Specifically, the VRR display, power button, and input support for ASUS and Lenovo handhelds have been improved, which is great.

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