Valve has released the latest update for SteamOS, version 3.5.5. This update represents a huge step forward and brings numerous important new features.
A highlight of the update are the new sliders that allow you to individually adjust color intensity and temperature. This feature gives LCD displays deeper and richer colors and expands the color spectrum immensely.
Excellent news for anyone who doesn't want to upgrade to the new OLED deck but is still looking for improved color reproduction.
New color settings for your Steam Deck with SteamOS 3.5.5
Additionally, HDR and analytics have been unlocked for use with compatible external displays, and VRR is now supported for both external displays and the Steam Deck Dock. The update also brings general improvements to the Steam Deck OLED, enables automatic mounting of external storage devices, and introduces updated graphics drivers. The speed at which the device wakes from sleep mode has also been improved.
For the more tech-savvy among us, there are now also new voltage offset settings to undervolt the Steam Deck. SteamOS 3.5.5 also benefits from an updated Arch Linux base, which promises better performance and updates for KDE Plasma in desktop mode.
Overall, this update represents a huge leap forward and it's nice to see these developments live.
For those looking for improved color reproduction or eagerly awaiting games like " Starfield ," SteamOS 3.5.5 will be the ideal choice.
Here are the changes in detail:
SteamOS 3.5.5 update changelog:
Advertisement
- Added Settings => Adjust Display Colors to adjust the color intensity and color temperature of the display. Settings can be adjusted by previewing a test image (above) or while the game is running.
- Native: The native appearance of the display colors (the color rendering for Steam Deck before this update).
- sRGB: Simulates the sRGB primary colors.
- Boosted: Simulates the appearance of a display with a wider color spectrum, resulting in increased vibrancy.
- HDR can now be enabled in the display settings if it is supported by the external display.
- Added HDR analysis to advanced display settings.
- VRR can now be enabled in the display settings if supported by the USB-C adapter. (Works with JSAUX docking stations )
- Reworked quick access scaling settings to separate scaling from filtering. Added stretch and zoom scaling as new options to deal with different aspect ratios.
- Fixed a long-standing issue where the internal display backlight would always stay on.
- Fixed touchscreen orientation while an external display is connected.
- Additional scenarios that avoid compositing reduce latency and stuttering when there are multiple overlays on the screen.
- Improved latency in certain situations where the application renders slower than the display refresh rate.
Generally
- Added support for Steam Deck OLED.
- Fixed an issue where certain workloads exhibited severe CPU performance issues unless SMT was manually disabled.
- External storage devices will now mount automatically when connected to the Steam Deck. To format or manage storage devices, use the new Device Management section in Settings -> Storage.
- Graphics drivers updated, with many performance and feature improvements. Improved performance for " Starfield ". Fixed model rendering errors in " Amnesia: The Bunker " and launch errors for " Immortals of Aveum " and " Kaiju-A-GoGo ".
- Improved Bluetooth connection stability, especially with multiple controllers.
- Sleep mode wake speed slightly improved.
- Improved 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 did not match their swapchain size (e.g. " Naruto Shippuden Ultimate Ninja Storm 4 ")
- Fixed physical dimensions reported to games, fixing some issues with aspect ratio sometimes being incorrectly detected (eg " Returnal ")
- Worked around an issue where "Allow Tearing" could cause severe stuttering when the performance overlay or other overlays appeared on the screen. Tearing is now impossible in such situations. The performance overlay should be disabled for best results.
- Fixed an issue where keyboard input was not recognized in Overwatch 2 .
- Controller Firmware: Fixed an issue that caused some thumbstick touch sensors to periodically lose contact.
