A new Steam Deck Client update was released that fixes some issues, as well as adds new support for controllers and improved performance. A crash with DualSense controllers has been fixed, while adding a large number of non-Steam games to a collection shouldn't fail anymore. We also have improved recording performance for games using Vulkan rendering, and dual gyros support has been added for the Switch Joycons in combined mode. There are also some new alerts that were added for people trying to use the Steam client on 32-bit versions of Windows.

You can download and install the new update through the System settings on your Steam Deck.

Steam Deck Client 10/2/25 Update Changelog:

General

• Added mitigations for Unity CVE-2025-59489, blocking a game launch through the Steam Client when an exploit attempt is detected.
• Fixed a crash when DualSense controllers are connected and idle.
• Fixed "\\" characters appearing in some news posts
• Added ability to switch tabs in the tabbed browser by pressing CTRL+TAB
• Fixed some cases where access to "Mark as private" game setting was unavailable.
• Fixed some cases where adding a large number of non-Steam games to a collection would fail.
• Fixed some "Friends & Chat" settings occasionally resetting to their default value temporarily after getting disconnected from Steam
• Fixed a case where a user's achievements would fail to display in the overlay when activated by a game.
• Fixed scroll arrow buttons on Post-Game Summary overscrolling to the end of the summary instead of the next non-visible item.
• Fixed a rare crash when constructing the menu for the tray icon on Windows.
• Fixed a case the client window could keep growing in size for WindowsBlinds theme users

In-Game Overlay

• Fixed a crash in D3D12 games that could sometimes be triggered by opening and closing sections of the overlay (like notes) rapidly. This could manifest as a game or gpu hang, was easier to trigger in some games than others, and was a new regression in this week's public client update and the last beta cycle. We will test this briefly in beta before shipping as a hotfix to all users.

Game Recording

• Improved performance when recording is on for some games using Vulkan rendering

Steam Input

• Added support for dual gyros when using Nintendo Switch Joycons in combined mode
• Fixed the "listen for binding" panel in the configurator
• Fixed the configurator being blank when opening a configuration for an uninstalled game that requires being installed to edit the configuration
• When authoring an official configuration for a Steam Input API game, use a setting under Settings->Developer instead of relying on the SetInputActionManifestFilePath API call

Streaming

• Fix cases where clicking "stream" did nothing.

SteamVR

• Fixed Steam Client notifications getting suppressed after you exited SteamVR. The suppressed notifications would appear inside your VR headset the next time you started SteamVR.

Accessibility

• Improved High Contrast view of game list search and app filter panel

Windows

• Added "End of Life" alert for 32-bit versions of Windows. Currently Windows 10 32-bit is the only 32-bit version of Windows supported by Steam.
  • The Steam client will continue running on Windows 10 64-bit and 32-bit games will continue to be supported.
  • Steam Client support for Windows 10 32-bit will end on Jan 1st, 2026 at 10am. See here for additional details.
• Added detecting if Secure Boot and a TPM are enabled on the current machine. This information is displayed under Help > System Information. It is now also collected when opting into the Steam Hardware Survey.
