It is a wrapper indeed, just like the Steam version is a 'wrapper' and you pay for that as well. I have an OLD pc from 2014 I use for FF, it's just an i5 4960k and a GTX 980...but it sits at 60fps all day long on 1920x1200, apart from maybe Limsa. My MacPro with RX 580 sits at around 35-45fps...20fps in Limsa. The wrapper just has so much overhead as activity monitors shows 100% usage of the GPU and only about 30% on the CPU.
