Valve has officially launched SteamOS 3.7.8, marking a significant expansion of its gaming operating system beyond the Steam Deck. This update introduces official support for third-party handheld gaming devices, including Lenovo’s Legion Go S and Asus’ ROG Ally series, as well as the original Legion Go.
Previously, enthusiasts had to rely on unofficial methods or alternative solutions like Bazzite to run SteamOS on non-Steam Deck hardware. With the release of SteamOS 3.7.8, Valve now provides an official recovery image and detailed installation instructions for these AMD-powered handhelds, signaling a move towards broader compatibility.
For Steam Deck users, the update brings several enhancements:
- Bluetooth Microphone Support: Users can now utilize Bluetooth earbuds’ microphones in desktop mode.
- Remote Wake-Up: The LCD screen can be turned on remotely using a Bluetooth controller, a feature previously exclusive to the OLED model.
- Battery Charge Limit: A new setting allows users to cap the battery charge at 80% to prolong battery lifespan, especially useful when the device is frequently docked.
- Performance Tweaks: Users can now frame-limit variable refresh rate displays and control the P-state frequency of certain AMD CPUs.
Under the hood, SteamOS 3.7.8 is built upon updated components, including a newer Arch Linux base, Mesa graphics drivers, and the Plasma 6.2.5 desktop environment.
Valve’s updated SteamOS FAQ indicates a strategic push to expand the operating system’s reach. The company is collaborating with select partners to develop officially licensed “Powered by SteamOS” devices. Interested parties are encouraged to contact Valve for more information about licensing SteamOS for their hardware.
This move comes amid ongoing speculation about Valve’s future hardware plans, including rumors of a wireless VR headset codenamed “Deckard” and potential SteamOS-powered living room consoles. The expansion of SteamOS support to third-party devices suggests that Valve is laying the groundwork for a more extensive ecosystem, potentially revitalizing the concept of Steam Machines.
With SteamOS 3.7.8, Valve not only enhances the functionality of the Steam Deck but also opens the door for a broader range of handheld gaming devices to join the SteamOS ecosystem, offering gamers more choices and flexibility in their gaming experiences.
