While I am seeing issues that are regressions with SU5, instability isn’t one I am seeing. There are many people in the forums reporting crashes, etc. so I am not saying “works on my rig so must work on all”. Just simply saying that the converse also isn’t true: “unstable on your rig does not mean unstable on all”.
I would suspect that the reason I am not seeing instability is because I have not installed anything from the community or 3rd parties. So if I was to recommend anything to those experiencing instability, it would be to go back to a vanilla state and see if the sim is stable.
That said, it doesn’t really bode well for MSFS2020 that Asobo’s update doesn’t play well with the ecosystem they are trying to build. In fact, I’d say it is yet another example of very poor strategy and execution.
To be a successful sim fort the long term, an ecosystem is really the thing that will either make or break this sim’s future. When a bunch of talented people, like the FlyByWire team, and invest time in producing something great for the community, and they do an update and it breaks this great 320 mod and they say “oops, we’ll just temporarily de-list it in the marketplace”?
That is just bad. So that is what I mean by “poor strategy and execution”.
Unfortunately, this sim is not yet in the place where updates can happen without impacting the ecosystem. So in my view that means we better get used to knowing how to return MSFS2020 to a vanilla state with no mods or 3rd party stuff.
