I have no experience of running FS20 on an Xbox so I can’t talk about using an xbox with Airbus and Boeing liners but this forum seems full of people with lots of issues especially when runing high fidelity liners.
The biggest issue with Xbox is the lack of access to all the user created content.
Any way, good luck with whatever you decide, sPK
