Bazzite is an OCI image that serves as an alternative operating system for the [Steam Deck](https://www.steamdeck.com/), and a ready-to-game SteamOS-like for desktop computers and living room home theater PCs.
Bazzite is built from [ublue-os/main](https://github.com/ublue-os/main) and [ublue-os/nvidia](https://github.com/ublue-os/nvidia), which means expanded hardware support and built in drivers are included. Additionally, Bazzite adds the following features:
- Proprietary Nvidia drivers included on the image
- Full hardware accelerated codec support for H264 decoding
- Full support for AMD's ROCM OpenCL/HIP runtimes
- Includes Valve's KDE themes from SteamOS
- [LatencyFleX](https://github.com/ishitatsuyuki/LatencyFleX), [vkBasalt](https://github.com/DadSchoorse/vkBasalt), [MangoHud](https://github.com/flightlessmango/Mangohud), and [OBS VkCapture](https://github.com/nowrep/obs-vkcapture) installed and available by default
- Support for [Wallpaper Engine](https://www.wallpaperengine.io/en) on KDE.
- [Distrobox](https://github.com/89luca89/distrobox) preinstalled with automatic updates for created containers.
- Automated duperemove services for pruning wine prefix contents.
- Uses [Google's BBR TCP congestion control](https://github.com/google/bbr) by default.
- [Input Remapper](https://github.com/sezanzeb/input-remapper) preinsalled and enabled (Available but default-disabled on the Deck variant)
- Helpful first-start installer provides an easy way to install numerous helpful applications and tweaks, including installing [CoreCtrl](https://gitlab.com/corectrl/corectrl) and [GreenWithEnvy](https://gitlab.com/leinardi/gwe).
- Nix package manager, matching evidence in SteamOS 3.5 of this potentially being available in a future release.
- Runs Steam and Lutris in a [custom Arch Linux OCI](https://github.com/ublue-os/bazzite-arch/) via Distrobox.
- Ships with a ported version of [System76's Scheduler](https://github.com/pop-os/system76-scheduler), providing automatic process priority tweaks to your focused application and keeping CPU time for background processes to a minimum.
- Features ported versions of most SteamOS packages, including drivers, firmware updaters, and fan controllers [from the evlaV repository](https://gitlab.com/evlaV)
- Comes with patches from [SteamOS BTRFS](https://gitlab.com/popsulfr/steamos-btrfs) for full BTRFS support for the SD card by default
- Ships with a ported copy of [SDGyroDSU](https://github.com/kmicki/SteamDeckGyroDSU), enabled by default
- Option to install [Decky Loader](https://github.com/SteamDeckHomebrew/decky-loader), [EmuDeck](https://www.emudeck.com/), and [ProtonUp-Qt](https://davidotek.github.io/protonup-qt/), among numerous other useful packages on installation
- Custom update system allows for the OS, Flatpaks, and Distrobox images to be updated directly from the Gamemode UI
- Steam and Lutris preinstalled on the image
- Comes with a default-disabled service for low-risk undervolting of the Steam Deck via [RyzenAdj](https://github.com/FlyGoat/RyzenAdj)
- Exclusively uses zram by default with the option to switch back to a swapfile and set a custom size if desired
- Tuned I/O scheduler to reduce starvation when installing games or during background duperemove processes
- Uses CFS scheduler parameters from [TKG](https://github.com/Frogging-Family/linux-tkg) for increased performance
- Applies SteamOS's kernel parameters and enables amd-pstate by default
Bazzite started as a project to resolve some of the issues that plague SteamOS, mainly out of date packages despite an Arch base and the lack of a functional package manager.
Despite this project also being image-based you are able to install any Fedora package straight from the command line. These packages will persist across updates. Additionally, Bazzite is updated daily with packages from upstream [Fedora](https://fedoraproject.org/) giving you the best possible performance and latest features - all on a stable base.
Bazzite ships with the latest Linux kernel and SELinux enabled by default with full support for secure boot and disk encryption, making this a sensible solution for general computing.
Ported SteamOS and ChimeraOS packages, among others used by Bazzite, are built on Copr in [this repo](https://copr.fedorainfracloud.org/coprs/kylegospo/bazzite/).
