Valve has introduced an update to the Steam OS 3.2 operating system that comes with the Steam Deck game console. Steam OS 3 is based on Arch Linux, uses the Gamescope composite server based on the Wayland protocol to speed up the launch of games, comes with a read-only root file system, uses an atomic update mechanism, supports Flatpak packages, uses the PipeWire media server and provides two interface modes (Steam shell and KDE Plasma desktop). Updates are only available for Steam Deck, but enthusiasts are developing an unofficial build of holoiso, adapted for installation on regular computers (Valve promises to prepare builds for PC in the future).
Among the changes:
- Implemented control of the fan speed by the operating system, which allows the user to more finely balance between frequency and temperature, adjust the behavior of the cooler depending on various usage scenarios, and minimize the noise level during inactivity. The previously used cooler control mechanism, which works at the firmware level, remains available and can be returned in the βSettings > Systemβ settings.
- Provided the ability to use a different screen refresh rate while running game applications. The frequency is automatically adjusted according to the specified parameters when the game is started and returns to its previous values ββafter the game exits. The setting is made in the quick access menu - in the Performance tab, a new slider has been implemented to change the screen refresh rate in the range of 40-60Hz. A setting is also provided for limiting the frame rate (1:1, 1:2, 1:4), the list of possible values ββin which is determined depending on the selected frame rate.
- In the information block displayed over the current image (heads-up display, HUD), the accuracy of video memory information has been improved.
- Added additional screen resolution options for games.
- For microSD cards, Quick Format is enabled by default.
