Flight Sim Labs has released update v11.0.1.326 for its A321ceo and A321neo series in Microsoft Flight Simulator. The update marks the first post-release refinement following the recent Pratt & Whitney (PW) A321neo expansion and is currently available through the Flight Sim Labs Control Center under the Experimental Channel.
According to the developer, this is an interim update primarily targeting performance optimisation, system stability, and general refinement. While not a feature-heavy release, the update introduces a wide range of targeted improvements affecting aircraft handling, internal systems, and visual elements.
A major focus of the update is performance. Flight Sim Labs implemented several optimisation strategies aimed at reducing both GPU and CPU load, with particular attention given to cabin and external model rendering. Texture sizes have been selectively reduced, and model complexity has been adjusted to lower VRAM usage without significantly impacting visual quality.
To further support performance-conscious users, the update expands the existing Cabin Lite option. This setting allows users to disable certain cabin elements that may otherwise impact memory usage, an adjustment especially relevant for users operating on hardware with limited graphical resources or those primarily flying in cockpit or external views.
Handling refinements are also included. Braking behaviour has been revised through updated pedal curve logic, intended to deliver smoother and more progressive deceleration characteristics. The developer additionally noted that further adjustments for low-speed stopping dynamics are planned for a future update.
Several flight-guidance and navigation-related corrections are part of this release. Flight Sim Labs addressed issues affecting SRS and LOC capture behaviour on the A321neo variants, improving autopilot and guidance consistency during departure and approach phases. Broader flight-guidance updates are reportedly undergoing validation.
System-level improvements span multiple aircraft subsystems, including FADEC logic, display management, flight management (FMGC), electrical behaviour, and TCAS functionality. The update also introduces a redesigned FMGC logging architecture, aimed at improving diagnostic capabilities and long-term stability.
Visual and model-related refinements are also included. These include refinements to fuselage modelling, texture corrections, engine visual adjustments, and further optimisation of the Cabin Lite model. Distinctions between CEO and NEO wing configurations were likewise updated.
Update v11.0.1.326 is available now via the Experimental Channel. No additional release timeline has been provided for migration into the stable branch.
