OK, I got a short flight in 2018.3.2, and it's not much different, perhaps slightly less twitchy in the C-172, but not a lot less. And I guess I'll still have to research how to get it to recognize various buttons on my Warthog (probably not soon, if ever -- I've got almost every aircraft control assigned to the Warthog in P3D and FSX). Hunting for info on the web I discovered that TrackIR is not supported because Natural Point doesn't allow the developers to use the APIs without paying (I've known of some court cases on APIs in other fields), which encourages folks to go elsewhere for head tracking.
