Key Features of SteamOS 3.7.0 Preview

The SteamOS 3.7.0 Preview represents one of Valve’s most substantial updates to date for the Steam Deck. With the integration of KDE Plasma, users can enjoy a more desktop-like experience, alongside other notable enhancements that increase the usability and performance of the device.
