"Steam Deck Firmware Update Introduces Safe and Easy Undervolting Controls"

The latest SteamOS 3.5.1 Preview for the Steam Deck handheld device now includes undervolting support, allowing users to enhance performance and energy efficiency. The firmware update also introduces safety measures to prevent bricking the device, automatically resetting voltage settings if they render the device inoperable. Undervolting AMD APUs can yield visible performance enhancements, and the update may potentially improve results. However, access to AMD PBS and CBS settings has been removed in the firmware upgrade.
