A new version of Bazzite Linux, version 43.20251210, has been released with improvements for gamers and streamers, including built-in HDR support and new CPU schedulers to reduce lag during games. The operating system comes with Steam pre-installed, making it easy to access your game collection, and includes user-contributed tools to make game launches faster and more tailored to gaming and streaming needs. Bazzite 43 also features integration with Lutris, a game launcher that can pull games from multiple sources beyond Steam, keeping them separate and clean during Steam sessions. The release bundles several commits and visual updates, solidifying the connection to this specific kernel branch, and upgrading should be straightforward for existing users.
Bazzite 43.20251210 released
A new version of Bazzite Linux, version 43.20251210, has been released and promises smoother action for gamers and streamers alike.
For users fresh to gaming or deeply familiar with it, the convenience is palpable right from launch. Bazzite includes Steam pre-installed, offering instant access if you've got your collection of games already downloaded. In addition to the basic setup, improvements like built-in HDR support help improve picture quality, and new CPU schedulers work to reduce lag during important moments in games.
The community aspect is also strong this time around. Many user-contributed tools and configuration tweaks are included, aiming to make game launches faster and the whole experience more tailored for both gaming and streaming-specific tasks.
One particularly intriguing element involves Lutris as a pre-installed game launcher. It cleverly pulls games from sources beyond Steam, like Xbox Game Pass via Battle.net, EA App titles, Epic Games Store purchases, GOG.com classics, games from itch.io, Rockstar or Ubisoft installers, and even older CD-based ones, but importantly keeps them separate and clean when you're in the middle of a Steam session. This integration feels pretty smart.
Under the hood of Bazzite 43, developers have worked on major packages to enhance system smoothness overall. The kernel has advanced to 6.17.7-ba20 now, with an associated firmware update dated back roughly to mid-October this year (version 20251021ba0-0). Crucially too, Mesa got a big upgrade recently from its earlier 25.2.x iteration, jumping straight over to version 25.3.0-1.
The release bundles several commits alongside visual image updates, solidifying the connection to this specific kernel branch (pinned at ba20) and seeing package revisions across familiar fronts like Gnome, KDE, HHD, and other supporting libraries.
If you're running Bazzite on your system, upgrading shouldn't be difficult. Simply firing up a terminal window provides straightforward commands for rolling back or applying the latest changes depending on whether you've been using an older branch specifically.
