Display Enhancements: One notable improvement in SteamOS 3.5.5 is the adjustment of the default color rendering for the Steam Deck LCD. The emulation of the sRGB color gamut now delivers a slightly warmer and more vibrant color appearance, enhancing visual experiences. Users can fine-tune display colors with the new Settings -> Adjust Display Colors feature, allowing customization of Color Vibrancy and Color Temperature.

For those craving high dynamic range visuals, Steam Deck now supports HDR for external displays, with additional HDR Analysis available in Advanced Display settings. Variable Refresh Rate (VRR) is also on the menu, provided your USB-C adapter supports it.

General Upgrades: Steam Deck OLED gets official support with the SteamOS 3.5.5 update. Additionally, the update addresses a CPU performance issue for specific workloads, ensuring a smoother gaming experience. External storage devices now auto-mount when connected, streamlining the user experience.

Graphics drivers have been updated, bringing performance boosts and fixes for specific games like Starfield. Bluetooth connection stability has been improved, along with faster sleep resume speeds. The ability to switch between controller and mouse/keyboard bindings by long-pressing Options adds a convenient touch to the Linux hid-steam driver.

Firmware Enhancements: Firmware 118 introduces voltage offset settings, providing more control over your Steam Deck’s performance. The Steam Deck Dock Firmware 121 follows suit, introducing Variable Refresh Rate (VRR) support and improving reliability when changing display modes via on-screen menus.

Updated Arch Linux Base: Beyond these device-specific upgrades, SteamOS 3.5.5 incorporates an updated Arch Linux base. This brings in newer performance, security, and stability fixes for the underlying packages supporting SteamOS. Highlights include a new window tiling system and improved Discover (app store/software manager) with enhanced search functionality.
