SteamOS 3.5 Beta Patch Notes: September 15, 2023
The "Beta" OS Update Channel has now been updated. This update is available in the Steam Deck Preview channel, and includes new features that are still being tested. You can opt into this in Settings > System > Steam Update Channel. It contains the following changes:

Display
    The default color rendering for Steam Deck has been adjusted to emulate the sRGB color gamut, resulting in a slightly warmer and more vibrant color appearance.
  • Added Settings -> Adjust Display Colors, to tune the display's Color Vibrancy and Color Temperature. The settings can be tuned with a preview of a test image (above), or with your running game.
    • Native: The native display color appearance (the color rendering for Steam Deck prior to this update).
    • sRGB: Emulate the sRGB primaries, in a smooth manner that does not introduce gradient clipping.
    • Boosted: Emulate a wider-gamut display appearance, resulting in increased apparent vibrance. May result in gradient clipping.
  • HDR can now be enabled in Display Settings if supported by the external display.
  • VRR can now be enabled in Display Settings if supported by the USB-C adapter.
  • Reworked Quick-Access scaling settings to separate scaling from filtering. Added Stretch and Zoom scaling as new options to handle different aspect ratios.
  • Fixed touchscreen orientation while external display is connected.
  • Compositing is now avoided in additional scenarios, reducing latency and stutter in situation with multiple overlays on screen.
  • Improved latency in certain situations where the application renders slower than the display's refresh rate.
General
  • Fixed an issue where certain workloads would exhibit severe CPU performance issues unless SMT was manually disabled.
  • External storage devices are now auto-mounted when connected to Steam Deck. To format or manage storage devices use the new device management interface in Settings->Storage.
  • Updated graphics drivers, with many performance and functionality improvements. Improved performance for Starfield. Fixed viewmodel corruption in Amnesia: The Bunker and launch failures for Immortals of Aveum and Kaiju-A-GoGo.
  • Improved Bluetooth connection stability, especially with multiple controllers
  • Slightly improved sleep resume speed
  • Implemented switching between controller bindings and mouse/keyboard desktop bindings by long-pressing Options in the Linux hid-steam driver, to match Steam's default Desktop configuration.
  • Improved fade transitions between applications.
  • The contents of the performance overlay can now be customized by creating a ~/.config/MangoHud/presets.conf configuration file.
  • Fixed a bug where some games could appear stretched if their window size didn't match their swapchain size (eg. Naruto Shippuden Ultimate Ninja Storm 4)
  • Fixed Disgaea PC needing to be tapped on before input works
  • Fixed physical dimensions reported to games, fixing some issues with an incorrect aspect ratio sometimes being detected (eg. Returnal)
  • Worked around a problem where Allow Tearing could cause heavy stuttering if the Performance Overlay or other overlays appeared on screen. Tearing is now impossible in such situations, and the Performance Overlay should be disabled for best results.
  • Fixed a problem where keyboard input would not be detected in Overwatch 2
  • Controller firmware: fixed an issue where some thumbstick touch sensors would lose touch periodically
Firmware 116
  • Added voltage offset settings.
  • Improved robustness of the Firmware Settings Reset chord (Volume Down + Quick-Access + Power) against some boot hang scenarios.
  • Fixed a rare issue that would set the processor TDP limit too low causing CPU and GPU frequencies to be stuck at 400 MHz and 200 MHz respectively.
  • Fixed an issue when the charging light would turn back on when plugged in for a while after fully charged.
Updated Arch Linux Base
  • This update pulls in the latest performance, security and stability fixes for the underlying packages that are the foundation for SteamOS
  • Most notably, this includes recent changes to KDE Plasma, Steam Deck's Desktop Mode. Full notes on these updates can be found on KDE's website here[kde.org]. Here are a few of the highlights:
    • New window tiling system
    • Updated Discover (app store / software manager) with a new homepage and improved search
    • Discover can now perform system updates from the desktop
    • Updated desktop widgets

Is there somewhere to download the 3.5 image? Trying to let Steam OS update itself nuked the partition and I can only boot into Windows now.

Apparently hearing comments that this update locks out your sd card until you reformat it if you use emudeck, dunno if I should update

Apparently you broke HDMI output to external displays. After the other major features you've steadily degraded I think I'll refrain from updating for awhile.

Is there any way to remove the symlink of the old microsd pathway?

Finally, colour temp and seemingly gamut controls to get away from the abomination that is the Deck's default image. Thank you for this.

I switched over to the preview channel and updated both the deck and the official dock, but now the dock no longer sends the display to my TV.

I also have a JSAUX dock which still works. Did this update brick my official dock?

Edit: rolling back to stable fixed it. I guess I'll just wait until this update is fully tested and released.

This update seems to have fixed wifi issues I was having, regardless of whether or not power savings were on or off. My experience with the Deck is a lot better overall with this update.

the same "reversed" effect happened to me: after the update I was no longer able to stream from my pc to deck in Remote Play. Downgrading to 3.4 fixed the issue.

Waiting for a more tested version.

1. When docked screen stays on ? I mean it's black but I see backlight bleeding, something is not right
2. Dock still does not switch off network card when deck is unplugged polluting network with garbage.

Where are these voltage offset options mentioned in the release notes???

They don't exist in the bios or system options.

For me i can no longer stream games from my PC to my Deck, the screen either gets black or the Steam logo is there spinning, i can sometimes get sound but i can not do any input. I can back out from the session and resume it but it gets to the point i just mentioned.
