The public release of X-Plane 12.4.0 is now available as a full release for everyone. This is being dubbed as their C-Check update, as it brings a lot of bug fixes and stability for the platform following a few releases that focused heavily on new features.
One of the biggest changes with 12.4.0 was the introduction of multi-threading for scenery. X-Plane can now distribute scenery preparation across multiple CPU cores, helping reduce bottlenecks when loading dense urban areas or complex environments. For users flying into detailed airports or photogrammetry-heavy regions, this should translate into smoother performance and fewer stutters during approach and taxi, particularly on modern multi-core systems.
On the aircraft side, the default Airbus A330-300 receives a substantial round of improvements. The electrical systems have been reworked, avionics logic refined, and display behaviour enhanced, with ACARS functionality now available through the third MCDU. General aviation also benefits, with the Cirrus SR22 gaining avionics refinements, better autopilot engagement logic, and clearer navigation displays. Other aircraft in the default fleet have also seen other improvements.
X-Plane 12.4.0 also introduces native Windows support for the Tobii Eye Tracker 5, allowing users to control cockpit view movement using head and eye tracking without relying on third-party plugins. For pilots who favour hands-free camera control, this integration provides a more seamless way to manage situational awareness in both GA and airliner cockpits.
The update is available now when you launch X-Plane 12. The full release notes can be found here. You can also see previous beta releases and the changes that came with them in our previous articles.
