The article was written by someone who didn't even bother to read/watch Microsoft's promo material. Lookup tables are a thing of the past. Microsoft has published two videos showcasing their new aerodynamics simulation[1][2].
There seems to be a lot of pushback from old-timers who have sunken thousands of $$$ into X-Plane and its expansions (from terrain packages to cloud visuals), many of which now look inferior to what Microsoft's new simulator offers out of the box.
That’s nice progress since FSX. I recall reading that new MSFS is compatible with FSX aircraft, which made me think they must rely on the same lookup tables at least as fallback.
While I stand corrected on lookup tables, the author does make a point on how his personal experience of flying the same aircraft as he does IRL does not compare to in-sim experience with MSFS, and does with XP. I saw similar feedback elsewhere, Wikipedia mentions it too in their reception section. If they actually implemented a sound physics model, this potentially could be addressed by tweaking it in future updates, so there’s hope.
For the record, I only bought XP11 itself for about $60 (no paid add-ons) and am flying the default Cessna. Most pro simmers appear to be invested in third-party aircraft for both sims, so I don’t know if there is so much unfounded bias.
