Although Valve does not plan to come up with a successor to the Steam Deck anytime soon, the company does ensure that the handheld is regularly provided with new firmware updates. Version 3.5.5 is now available and this update adds a lot of new features.
Not everyone was happy with the color intensity of the Steam Deck’s screen. You had to live with this, because there was no option to change this. Thanks to the latest update, this option is now available. If you’ve connected your handheld to an external monitor with VRR and/or HDR support, the Steam Deck now supports that too.
Update 3.5.5 brings with it many more additional features and adjustments, which are as follows:
- The default color rendering for Steam Deck LCD 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.
- Added HDR Analysis to Advanced Display settings.
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 a long-standing issue where the internal display backlight would always stay on.
- 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.
- Added support for Steam Deck OLED
- 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
- Added voltage offset settings
