It runs fantastically well on a series S too. I’ve bought a few airports and aircraft so far. I’ve not experienced many problems /CTD’s really. The obly one is the avionics screens going blank sometimes randomly, usually on longer flights, usually with the A320 (1.30-2 hrs). That is very annoying but they are aware of it and are fixing it.
If I sit and think about it logically for a minute, the game is a triumph of what can be done with very little. It’s amazing that it’s on the Xbox at all. Especially the Series S.
