I am not an X-Plane pilot, but X-Plane 11 does not support 3D water either, does it?
I don't know if it is called 3D water but in X-Plane you can fly seaplanes.
That is what I expected to see in FS4 because in FS2 there is a tiny bit of water.
Its not all that good either. Load times are abhorrent, photogrammetry is crap, stutters and freezing,no mouse sometimes, CTD's.
You must have bad luck with your sim. I don't recognize the things you mention.
But in the end we have a choice in sims and that is fine for everyone.
