Core Update Overview
CachyOS, an Arch-Linux-based gaming distribution, released its April 2026 ISO snapshot in early April. The image, hosted on CachyOS.org, adds new hardware support, switches the default graphical package manager from Octopi to Shelly, activates DNS-over-HTTPS, introduces a vRAM-management toggle based on Valve’s graphics work, and changes the default NVMe I/O scheduler to Kyber. The update also enables os-prober by default and configures fingerprint-scanner authentication for sudo commands.
Recent Momentum
In early 2026, CachyOS displaced Arch Linux as the top-ranked distro on ProtonDB, marking a surge in its gaming-oriented user base.
Timeline
- Early 2026 – CachyOS becomes the leading distro on ProtonDB for Linux gaming.
- April 2026 – New ISO released with Shelly, fingerprint-sudo, DNS-over-HTTPS, and performance tweaks.
Key Feature Highlights
- Shelly GUI – Provides a graphical interface for installing packages from the AUR, Flathub, and AppImages, simplifying setup for users new to Arch.
- Fingerprint-based sudo – The `chwd` utility auto-configures fingerprint readers, allowing sudo authentication via biometric scan.
- DNS-over-HTTPS – Enabled by default, encrypting DNS queries for enhanced privacy.
- vRAM management toggle – Leverages Valve’s graphics-memory optimizations to improve performance on GPUs with limited video RAM.
- Kyber NVMe scheduler – Replaces the previous “none” setting, delivering faster storage responsiveness.
Official Statements & Responses
The CachyOS development team characterizes the April snapshot as a polished, gaming-focused release that streamlines package handling and hardens superuser security. Release notes highlight Shelly as a contemporary redesign of the Arch Linux package manager, note fingerprint-sudo as an extra security layer, and point to the Kyber scheduler and DNS-over-HTTPS as steps toward better responsiveness and privacy.
Verbatim Quotes

Impact on Gaming Linux Community
Together, the new package manager, biometric sudo, and kernel-level performance tweaks lower the entry barrier for gamers moving to Linux. Faster NVMe I/O, improved GPU memory handling, and encrypted DNS boost gameplay fluidity and privacy, while fingerprint authentication reduces reliance on passwords for privileged actions.
Updating to the April Release
Existing CachyOS systems can upgrade with `sudo pacman -Syu`. New users should download the ISO from the April 2026 blog post on CachyOS.org.
