FSLabs has recently issued a new experimental update to their A321ceo and ceo for Microsoft Flight Simulator 2020 and 2024, focusing on increasing stability, improving visual performance, and improving the handling, among other things.

Update v11.0.1.309 aims to improve performance and lower VRAM usage, ensuring better headroom for users running very high resolutions or rocking cards with little VRAM to spare. Such extra headroom should warrant better stability in video memory-constrained environments, like approaching a demanding airport on top of a photogrammetric area.

They have also mitigated certain CTDs that occasionally happen with very specific TCAS traffic situations and aircraft reloads. The steps taken to mitigate those should increase the overall robustness of their code, making it much more reliable.

FSLabs has also worked on correcting an issue affecting the yaw behavior during the landing roll and retuning brake effectiveness based on measured stopping distances from real aircraft. These tweaks should bring more authenticity to the post-touchdown phase.

‍

Systems were also improved, with FMGC protections added, further improvements to the NEO engine logic, ROPS behavior, and many smaller fixes.
