Oh yes, X-Plane is very resource intensive. It is a simulation, thus it doesn’t make much sense to compare its FPS numbers against typical gaming software. Maxing at ~60 FPS is reasonable, given your system specs.
It begs the question, why you do need/want more?
In my opinion, X-Plane 11 can function smoothly between 30-40 FPS. High 20s still provides acceptable margin of variability; while below 20 is unusable. To maximize enjoyment out of my hardware, I’d much rather aim for higher rendering settings, at an acceptable framerate.
