Confused on Steam Play and Proton? Be sure to check out our guide.

Getting a console-like big-screen experience with Linux gaming was a thing with SteamOS until Valve stopped updating it, then came along GamerOS to carry the torch which has evolved again with a new name of ChimeraOS.

ChimeraOS has the same idea just a fancy rebranding, to remove the terrible GamerOS naming. Nice. It also now has an actual website that's a bit more fancy.

For those not aware of what it actually does: it gives you an experience that boots directly into Steam Big Picture, powered by Linux, for an improved couch-gaming setup. However, it's a lot more than that. It has a built-in web app to manage installing non-Steam games known as "Steam Buddy", enabling you to run games from GOG, emulators and many more services.

Here's all the main changes for what's now ChimeraOS 25:

Key components:
- Linux Kernel 5.12.12
- Mesa 21.1.3
- NVIDIA 465.31
- steamos-compositor-plus 1.8.3
- Steam Buddy 0.11.2

- Rename to ChimeraOS
- Updated installer with wifi support
- Added basic MangoHud configuration support via Steam Buddy
- Added racing wheel support
- Fixed bluetooth pairing through the Steam UI
- Fixed high CPU usage when MS Xbox controller dongle is plugged in
- Added Mr. Rescue, Sonic 3: Angel Island Revisited, Cave Story NX to Flathub
- Added Proton 6.8 GE-2, 6.9 GE-2, 6.10 GE-1
- Added media key support
- Improvements to updater reliability
- Improved reliability when starting flatpak/flathub apps
- Restore default steam play settings for a game when user override is removed
- Merged Steam Tweaks into Steam Buddy
