FSLabs – Update 11.0.1.326 Now Available!

Flight Sim Labs is pleased to announce the release of v11.0.1.326 for our A321ceo and A321neo series, marking the first update following the PW A321neo release.

This is an interim update primarily focused on performance, stability, and refinement, alongside a wide range of targeted system, handling, and visual improvements driven by both internal testing and customer feedback. This update is available now through the Flight Sim Labs Control Center in the Experimental Channel.

A major focus of this release has been improving overall performance through strategic reductions in texture sizes and optimization of both GPU and CPU load, particularly within the cabin and external models.

In support of these performance gains, we have introduced a multi-stage cabin and model optimization strategy. Users now have the option to disable performance-impacting cabin items entirely via the Cabin Lite option in the Control Center, significantly reducing VRAM usage when the interior is not required.

For external views, we have implemented model-level optimizations that substantially reduce memory and polygon overhead compared to the fully detailed internal cabin representation. At a deeper technical level, we have reduced overall model node counts by intelligently grouping elements that do not require individual nodes, improving rendering efficiency without impacting visual fidelity. Finally, targeted texture resolution reductions have been applied where appropriate, delivering measurable memory savings while preserving overall visual quality. We will, of course, continue to drive further improvements in these areas as required.

This update is available now via the Experimental channel in the FSLabs Control Center.

As always, thank you for your continued feedback and support — it directly shapes the refinement and direction of our development.
