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.
