ChimeraOS is a Linux distribution aimed at gamers who primarily want a more console-like big-screen experience. A new release with ChimeraOS 28 is now available.
With this fresh upgrade it comes with some freshened up internals like Linux Kernel 5.15.5, Mesa 21.2.5, NVIDIA 495.44, RetroArch 1.9.13 and updates to their own built-in apps and tooling. Additionally there's now improved support for Xbox controllers connected via Bluetooth, an issue with the chimera app server crashing under certain conditions when loading MangoHud configuration files was solved and they also fixed an issue with the system updater which could result in an unbootable system under certain conditions.
What will be interesting to see is what happens with ChimeraOS once SteamOS 3 gets released. Since we know Valve will be releasing it as a standalone system, just like they did before and it will come with the new Steam UI that will replace Big Picture mode.
