SteamOS

There were a few new SteamOS updates on the Preview and Beta branches to implement some bug fixes and updates. The Beta and Preview branches both got a fix for the fan speed reverting to BIOS control, which resulted in high fan speeds. As for the SteamOS 3.9.1 preview, we also have fixes for the Steam startup video, framerate limits being lower than intended on some external displays, and some specific fixes for Forza Horizon 6 on the Legion Go 2 and suspend/resume for RDNA 1 and RDNA 2 GPUs.

You can access the beta or preview channel by going into the System settings on your Steam Deck and changing the updated channel to "Beta" or “Preview” respectively.

SteamOS 3.9.1 Preview Update Changelog:

General

  • Fixed a system crash when launching Forza Horizon 6 on Legion Go 2
