We have just shipped an updated Steam Client to the Preview/Beta channel.

General

• Fixed a bug that sometimes caused an empty "Steam Family Activity" group to appear in notification settings

Remote Play

• Improved the automatic Pyrowave bitrate calculation to improve visual quality

• Added convars @PyrowavePSNR and @PyrowaveHeightFactor to tune automatic bitrate calculation (see https://github.com/Themaister/pyrowave/blob/master/eval-results/objective-bitrate-evaluation.md for details)

• Pyrowave manual bitrates can be increased up to 1 Gbit/s (more bandwidth increases latency!)

• Pyrowave bitrate has been reset to the automatic default

• Fixed gradually increasing video latency when using Pyrowave on slow network links

• Reduced audio dropouts when using Pyrowave

• Added a dialog to recover if your network isn't able to handle current streaming settings

• Added a Steam menu option to stop desktop streaming

Steam Input

• On Linux switch to reshuffling gamepad input when the last running game exits instead of on game launch to avoid issues when running multiple apps at the same time

Game Overlay

• Fixed crash when Vulkan games recreate their swapchain

Steam Controller Firmware

• Fixed an issue where some Bluetooth BLE connections could disconnect repeatedly, especially on Steam Deck

• Improve the time needed to fully connect the device in Steam

• Fixed an issue where pairing via a puck connection could fail

We have just shipped an updated Steam Client to the Preview/Beta channel.

General

• Fixed clicking the buttons in the footer causing the glyphs to change back to gamepad

• Fixed a clicking the back button in the footer not working if nothing on the page had digital navigation focus

• Fixed the Steam logo spinner moving during the login flow

• Added delaying dimming the screen or displaying the screensaver when the Steam Store, web browsers or other apps request to disable monitor sleep and screensavers while playing video.

Steam Input

• Added support for the user-invoked On-Screen Keyboard in the desktop overlay

• Fixed issues with button and slider sizing in the configurator when opened in the desktop overlay

We have just shipped an updated Steam Client to the Preview/Beta channel.

General:

• Fixed a regression that caused non-Steam games to fail to launch.

• Fixed the onscreen keyboard not working the first time it is invoked on desktop.

Remote Play:

• Improved color accuracy when streaming an OpenGL game.

We have just shipped an updated Steam Client to the Preview/Beta channel.

General:

• Fixed the Recordings & Screenshots dialog not showing all games that have related screenshots in the game filter dropdown.

• Improved the text layout in achievement notifications when the name, description or both wrap across multiple lines.

• Fix some cases of header/footer flicker and invisibility during the first seconds after waking from sleep.

• When waking from sleep with a game running but the account now playing elsewhere:

  • Provide an option to exit the local game.

  • Go back to sleep if there is no input for 60 seconds.

• Fixed issues with trackpad typing if the trackpad is touched while the onscreen keyboard is opening

Steam Input:

• Improved the consistency of trackpad sensitivity between Steam Deck and Steam Controller

• Fixed cases where the Virtual menu modes could show the wrong activation type if it was created in the standalone menu vs from a controller source

• Implemented a version of the "Reorder Controller" dialog for Steam Input API games. Note - this disconnects the controllers temporarily so older games which do not handle hot plugging properly can lose controller input

• Additional polish for the multibinding page

• In the desktop UI overlay the desktop config will now be applied. For most gamepads this will not be a difference in behavior because they have a blank desktop config, but Steam Controllers or devices that have setup a custom desktop config will have mouse input to click on things in the overlay.

Remote Play:

• Improved color accuracy when streaming from a Windows computer

• Fixed the mouse cursor when streaming from Linux using the SteamRT3C client

• Fixed a capture lockup when streaming from pipewire on Linux and SteamOS

• Reduced Pyrowave latency when streaming from pipewire on Linux and SteamOS

SteamRT3 Experimental Beta

• Fixed Steam overwriting PATH, LD_PRELOAD, and LD_LIBRARY_PATH variables when launching games.
