The 850 creates a lot of stutters and some weird mouse movements in 2024. It’s the only JustFlight aircraft I own, currently.
It hasn’t been updated to 2024, hopefully soon.
With the latest SU1 Beta update half of the cockpit animations for the autopilot don’t work anymore (the indications on the EFIS and also the lights for the buttons like HDG or NAV). The autopilot still works but it’s hard to tell what’s active.
Otherwise it still seems to work fine.
