I have bought and tested EHRD from RDPresets, but this version of the airport has very low performance, when i compare it to the hand crafted version that is standard in MSFS.
The hand crafted version of Asobo gave me 42 to 45 fps and the version of RDPresets 20 to 25 fps.
So that is a severe drop of performance.
I had bought it because of a few changes in the layout compared to the Asobo version, so it could work better with GSX Pro. But because of the severe drop of performance this purchase was a waste of money.
