Microsoft Flight Simulator 2024 flighting update 1.5.7.0 is on track to be released to the public flight groups on all platforms today (June 13). Please note due to some last minute delays with our publishing pipeline, it may still be several hours before the update shows up. We are working to resolve the issues with the publishing pipeline now, but are posting these release notes in advance as it’s unclear precisely when the update will become available.
Multiple active investigations are in progress for the performance issues reported on Sim Update 3, but we need your help!
We’re continuing to narrow down cause of the performance issues, and have added additional telemetry to the latest SU3 flighting update (1.5.7.0) to aid our investigation. 
Please note 1.5.7.0 will cause severe performance degradation around large airports and when restarting flights (most severe on Xbox Series X|S) . However, the data and feedback you provide is critical to solving these issues.
If you no longer wish to participate in Sim Update 3 flighting, please follow the steps at the bottom of this message to opt-out.
Thanks so much for your continued support!

RELEASE NOTES Sim Update 3 Beta - 1.5.7.0
If you are playing on PC, outdated packages in your community folder may have an unexpected impact on the title’s performance and behavior.
If you suffer from stability issues or long loading times, move your community package(s) to another folder before relaunching the title.

- Take a screenshot with DFPS enabled
- Send the report to the developers by navigating to Options > General > Experimental > Create a report
