SteamOS 3.5.1

Welcome to our in-depth exploration of SteamOS 3.5.1, the latest software update from Valve. In this article, we'll cover the new improvements, bug fixes, and exciting features that come with this update. Whether you're a gaming enthusiast or a Steam Deck user, this update promises to enhance your experience.

What Is SteamOS 3.5.1?

If you're not already familiar with SteamOS, it's a Linux-based operating system developed by Valve, designed to cater to gamers and, in particular, those who own a Steam Deck. Steam Deck is a highly successful handheld gaming device that has captured the hearts of many gamers.

Now, Valve has released a new version of SteamOS: SteamOS 3.5.1. This update brings not only bug fixes but also an exciting new function that has the potential to improve both the battery life and performance of the gaming handheld.

The New Features and Improvements

Undervolting for Enhanced Performance

The headline feature of SteamOS 3.5.1 is undoubtedly the introduction of undervolting. This intriguing feature allows users to supply the APU (Accelerated Processing Unit) with less voltage than originally specified. The success of undervolting depends on various factors, including a bit of luck. The specified voltage can be considered as a minimum requirement, but due to manufacturing tolerances, some APU chips can operate perfectly well with less voltage.

Stable operation at a lower voltage results in reduced waste heat, which, in turn, combats throttling – a common issue in gaming devices. Additionally, for a handheld device like the Steam Deck, lower power consumption is a significant advantage, as it directly contributes to longer battery life.

Bug Fixes and Enhanced Functionality

Besides undervolting, SteamOS 3.5.1 comes with a slew of bug fixes and various new features, both major and minor. Some notable changes pertain to the use of an external display, particularly the inclusion of HDR (High Dynamic Range) functionality. Previously, HDR output was unavailable for 32-bit programs, but this update rectifies that limitation.

One lingering bug that frustrated users was the issue of the internal display staying active even when an external display was in use. This problem has now been resolved, providing a smoother experience for Steam Deck users.

Furthermore, problems with the desktop mode have been addressed. Errors related to color display, particularly those that arose when switching to the plasma desktop, have been fixed. This ensures a more seamless transition between different modes of use.

Additionally, SteamOS 3.5.1 addresses a bug associated with memory cards, which could occur due to faulty file systems. These bug fixes contribute to an overall more stable and user-friendly gaming experience.

Why You Should Upgrade to SteamOS 3.5.1

If you're a Steam Deck user or a gaming enthusiast, upgrading to SteamOS 3.5.1 is a no-brainer. The introduction of undervolting alone can significantly improve your gaming experience. It not only enhances performance but also extends the battery life of your device – a win-win situation for any gamer on the go.

The bug fixes and additional features, such as HDR support, further enhance the overall usability of the Steam Deck. Say goodbye to annoying bugs and glitches that might have affected your gameplay in the past. With SteamOS 3.5.1, you're in for a smoother and more enjoyable gaming experience.

How to Get SteamOS 3.5.1

Now that you're excited about SteamOS 3.5.1, you're probably wondering how to get your hands on this update. The good news is that it should be available to all users. However, keep in mind that this version is currently in the beta stage. To access it, you need to switch to the Steam Deck Preview channel, as described in the changelog.

It's essential to be aware that beta software may not be entirely bug-free, so exercise caution when upgrading. Nonetheless, the potential benefits in terms of undervolting and bug fixes make this update well worth considering.


In conclusion, SteamOS 3.5.1 is an exciting update for Steam Deck users and gamers in general. With undervolting, bug fixes, and enhanced features, it promises to take your gaming experience to the next level. Whether you're a hardcore gamer or a casual player, this update is worth exploring.
