I’m also seeing a performance deterioration over time that I wasn’t seeing prior to the update. Both my flights have been about 1 hour, and I’ve lost about 30% of my frame rate on both flight. I had to restart the sim after my first flight because the fps stayed in the crapper after my first. On restart, it was fine. On approach now for my second flight, and my fps is again about 30% lower than it was at the start of the flight, and about 30% lower than it typically is here.
EDIT:
Frame rate plunged down even lower as I was coming in to about 5 NM. Then CTD on 1 mile short final.
