Definitely get the G1000nxi that is absolutely a no brainer, but skip any and all airports and scenery add ons on Xbox. They are terrible and use way too much Xbox memory and cause stability issues on a console that borders on regular memory leaks as is.
Sim update 6 is too perfect on a Series X now you will only get frustrated. I’ve deleted literally all of mine and it immediately got rid of performance issues on Xbox when in the area of those airports and/or scenery add ons from third parties from marketplace.
This isn’t unique to SU6 either so it’s not dependent on the dev updating their add ons; it has always been the case on Xbox. Approaching a custom third party airport is a crapshoot for a ctd and massive fps drops lol.
Edit: Came back to edit as I was a bit harsh there. The add ons themselves are not terrible, many are in fact beautifully done. It’s just that the sim on Xbox really struggles to handle all of the data at once using system memory and my experience has been quite negative with ctds and frame drops around most scenery or airport add on content and in my case was improved significantly or entirely by removing the content. They look lovely in most cases, but I cannot recommend their use until the memory leak raised by Asobo last week is addressed.
Just wanted to add that as the third party devs really do do a nice job, it’s just a platform limitation at the moment.
