Valve has released a fresh update for the Steam Deck handheld gaming console, known as SteamOS 3.5.1, specifically designed for devices enrolled in its Preview channel. It’s important to keep in mind that beta software, including this update, may still have some issues that need to be resolved. Nevertheless, this update brings a variety of intriguing changes and fixes, which can be reviewed below.

One standout feature of this update is the introduction of undervolting controls. This means that the APU (Accelerated Processing Unit) can receive less voltage than its default specification, potentially reducing heat generation. For those who like to tinker, undervolting can enhance system stability, improve battery life, and potentially prevent performance throttling.

It’s worth noting that the effectiveness of undervolting can vary due to manufacturing variations. This happens because no two CPUs, or APUs in this case, are exactly the same, even if they are the same model. This is because the manufacturing process is not perfect. As a result, some CPUs may be able to handle lower voltages than others without becoming unstable.

The update addresses several issues and introduces various improvements, particularly related to external displays. Previously, HDR output wasn’t possible in 32-bit applications, but this has been resolved. An annoying bug that kept the internal display backlight on constantly has also been fixed. For users who utilize the desktop mode, problems like erroneous color displays during transitions to the Plasma Desktop have been addressed.

Additionally, the update resolves issues with memory cards that had problems with faulty file systems, offering a more seamless experience to Steam Deck users.

In related news, a new Steam Deck might be coming sooner than expected. Previously, Valve stated that it has no plans to release Stream Deck 2 before 2025, however, a recent certification has revealed a refreshed version under development with a better WiFi modem, better battery life, and more.
