Msfs 2024 Beta Testing. It's never too late for testing, anyway. The microsoft flight simulator 2024 technical alpha is now live, and content creators are already streaming their first experiences with the new sim.
If you go into the xbox insider hub, under previews there is one for msfs and you select it and press ‘join’. It doesn’t matter that a couple of the versions flopped in that 40 year period (windows me and windows 8 did too), msfs (2020) has been in dev since 2014, it’s 10 years.
