The latest Bazzite stable release introduces a new dmemcg-booster service for VRAM prioritization and adds a Vulkan low-latency layer, two changes aimed squarely at squeezing more performance out of gaming workloads on this immutable Fedora-based distribution. The 44.20260605 build also ships a new uresourced-dmemcg variant on GNOME images, applying memory cgroup tuning that favors foreground graphics processes.
Kernel coverage jumps from 6.19.14-ogc5.1 to 7.0.9-ogc3.2 in this build, paired with Mesa 26.1.0 and a major Nvidia Open driver bump from 595.71.05 to 610.43.02. The Nvidia LTS branch advances to 580.159.04, and KDE Plasma ticks up to 6.6.5. Userspace tooling gets refreshed across the board, with btrfs-progs hitting 7.0, SDL3 at 3.4.10, PipeWire at 1.6.6, and Tailscale jumping to 1.98.4.
Steam Deck users get several quality-of-life fixes, including a corrected return-to-gamemode script, an inputplumber target swap to vhci deck, and policykit exceptions for gamescope-session helpers. Selectable CEC modes are now exposed in the Bazzite Portal so users can choose how the system signals HDMI-attached displays. The Sunshine remote streaming integration has been migrated from a native package to a Flatpak managed through ujust, and a Firmware Flatpak is now bundled so device firmware updates can be triggered from a GUI rather than the command line.
A command injection vulnerability in the GNOME Nautilus Add to Steam extension was patched in PR #4950. The release also adds backports of the bees Btrfs deduplication daemon as a packaged option, while removing legacy components like xpadneo, OpenRazer's kernel module, and the GameMode RPM in favor of Flatpak alternatives. Existing users can pull the build with bazzite-rollback-helper rebase stable, and the full commit log lives on the Bazzite GitHub.
