The popular Arch Linux based CachyOS operating system is out with its “July 2025” update for providing the latest innovations for this performance-optimized, feature-rich Linux distribution.
CachyOS July 2025 now allows users at installation time to choose the user’s default shell. Users can choose between Fish and Zstd shell options or otherwise defaulting to Bash if neither is selected.
Those using the KDE Plasma desktop on CachyOS are now defaulting to using Wayland rather than the X.Org Server. Plasma X11 still is available as a fallback for those unable to run the Wayland session.
CachyOS is also now including Fwupd by default for the KDE Plasma and GNOME desktop installations.
The mesa-git package on CachyOS also now includes the currently-pending merge request around Anti-Lag 2 support for enhancing latency for supported games. This merge request remains pending against Mesa for implementing VK_AMD_anti_lag as an implicit Vulkan layer.
The Proton-CachyOS package also gained support for ANti-Lag 2 and the PROTON_FSR4_UPGRADE environment variable for FSR 3.1 games to be upgraded to using FSR 4.
Lastly, CachyOS Handheld Edition now supports the Lenovo Legion Go.
