Steam Deck Gets New Update

Valve has released a major SteamOS update for the Steam Deck, marking one of the most substantial patches in recent months. The September 9 client update brings over 30 improvements, many of which were previously tested in the beta channel, now available to all users.

The September 9 Client Update now brings those improvements to the stable channel, granting all Steam Deck users access to a sweeping set of upgrades, while Valve also doubles down on supporting other SteamOS devices like the Lenovo Legion Go S. Over 30 general enhancements are part of the update, including a new Customization tab that’s been added to game properties, letting users assign custom-sort titles in their libraries. Library startup performance has been improved too, especially for users with non-Steam games, and performance profiles now switch faster.
