A month and a half after its previous May release<\/a>, powered by the latest and greatest Linux kernel 6.15<\/a>, the Arch-based gamers-focused CachyOS has announced its fifth ISO snapshot for the year.<\/p>\n\n\n\n

One of the most notable additions is the ability to choose a preferred shell during installation, deciding between pre-configured Fish<\/a> or Zsh setups, or sticking with a plain-vanilla Bash<\/a> environment. Fish remains the out-of-the-box default, yet the extra choice means fewer post-install dot-file gymnastics for users who already swear by Zsh.<\/p>\n\n\n\n

Under the hood, following user reports of \u201ctrigger-happy\u201d out-of-memory kills, CachyOS has removed its integration with systemd-oomd, opting instead for the kernel\u2019s native memory-pressure controls. The distribution\u2019s keyring workflow has also been hardened to retry more aggressively when key downloads hiccup.<\/p>\n\n\n\n

For Plasma users (the update ships with v6.4.2<\/a>), the installer now defaults to a Wayland session. However, if the hardware cannot handle it\u2014think legacy NVIDIA cards\u2014the “plasma-x11-session<\/em>” package is automatically pulled in, preventing black-screen surprises.<\/p>\n\n\n\n

\"CachyOS<\/a><\/figure>\n\n\n\n

At the same time, fwupd<\/a>, an open-source utility designed to make updating firmware on Linux-based systems easier and more automatic, now comes pre-installed on both Plasma and GNOME images, allowing firmware updates straight from Discover or GNOME Software.<\/p>\n\n\n\n

On the graphics stack, mesa-git now carries the merge request that enables AMD Anti-Lag 2\u2014Team Red\u2019s answer to NVIDIA Reflex\u2014across Vulkan titles. CachyOS\u2019 Proton build picks up matching patches, so Steam gamers<\/a> can toggle the feature without external scripts.<\/p>\n\n\n\n

Proton-CachyOS also introduces the environment variable “PROTON_FSR4_UPGRADE=1<\/em>.” When set, Proton will fetch AMD\u2019s latest FSR 4 DLL and transparently replace older FSR 3.1 libraries, sparing users from manual DLL shuffling. A similar shortcut debuted in Proton GE 10-9 only yesterday, underscoring how fast FSR 4 is propagating through the Linux ecosystem.<\/p>\n\n\n\n

Additional upstream Wine-Wayland and anti-cheat patches round out the gaming story, promising smoother input latency and fewer \u201cunsupported driver\u201d pop-ups in multiplayer titles.<\/p>\n\n\n\n

Lastly, CachyOS\u2019 Steam-Deck-style Handheld Edition now boots cleanly on the Lenovo Legion Go family, including the new cost-conscious Legion Go S model. Given the current Prime Day buzz around that device, Valve-style gaming on Lenovo hardware just became easier for users unwilling to reflash Windows or wrestle with device trees.<\/p>\n\n\n\n

As an Arch-based Linux distro<\/a>, existing users can grab all these improvements with a simple sudo pacman -Syu<\/code> command. For those opting for a fresh install, the updated ISO files are available for download via CachyOS\u2019s SourceForge mirrors<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
