It’s certainly about time this was covered properly. Marketplace airports are a total mess in xbox. SU9 so far is even worse than SU8, in some cases where I got occasional crashes I now get 100% failure rate. eg. Reproducible CTD at Impulse Simulations YPAD Adelaide Airport
Even some of the Asobo modelled airports have poor performance.
It’s so frustrating it seems to get worse with each sim update and I’ve yet to even see an acknowledgment from Asobo. But then the Xbox mouse problem was ignored for most of a year and is still not fixed properly. It seems xbox users, like PC VR users are not a big enough market share to make it important enough.
