that is exactly how it goes. I have exact coordinates of where it happens as an example: fly over Torrey Pines gliderport in san diego. I paraglide there often and when I fly there on the sim just over the landing zone cliff, BOOM… down to 20 stuttering FPS… it is clinical. I REALLY REALLY want to know from Asobo what is causing this… No word yet from them? this has got to be a trivial thing to find for them as it is not dependend on system or specs: it is ALWAYS there for anyone.
