iniBuilds has recently issued a new update to their A350 Airliner for Microsoft Flight Simulator 2020 and 2024, bringing extensive bug fixes, performance improvements, and a refined audio experience.

Update v1.1.7 has a strong focus on performance improvements, and they are pleased to report significant gains across the board. Their team has worked very hard to optimize every area of the airplane, which will hugely benefit those on weaker hardware.

Based on customer feedback, they have developed a new performance-friendly cabin as the default, eliminating the need to disable the cabin entirely for performance. However, the option to turn the cabin off will remain available for those who wish to do so.

​

They have also decided to sunset the cabin packs from 1.1.7 onward, focusing their efforts on further optimizing the core product experience. iniBuilds also clarifies that custom cabin livery textures are still fully supported across all cabin variants.

​

Furthermore, they have reduced the quality of some textures on the A350 while ensuring they do not impact the visual fidelity in any way.

​

Their 3D model also underwent a slight optimization process, significantly reducing the node count by several thousand, resulting in a positive improvement to main thread performance. The wingflex system was also changed to a more optimized method, reducing the number of “bones” by 50%.

​

The optimization work also extended to the LODs, which, although not heavily contributing to performance gains, helped somewhat, making the transitions smoother.

​

The average framerate has improved by 19.6% on their test system, and the 1% lows went up by 58%.

​

The sound department has also seen improvements, as seen below:
