Hi,
I have some areas with ortho scenery and some areas with default scenery. When in areas with default scenery, my fps is ~40. In the places I have the ortho scenery, fps is fine after loading the plane, but it drops to less than 10 and stays there as soon as I turn on the battery. In all other planes my FPS is actually higher with the ortho scenery.
Specs:
i5 7300HQ
8GB RAMs
GTX 1060
No plugins.
