Any other reports of framerates that drop significantly over time. I am getting great framerates at the start of the flight (QW 787, PMDG 747) but over time the framerates drop to single digits. The is kind of a stutter drop ever 4 or 5 seconds. so the frames will be 30, 35, 40, 50 and the down to 6, 7 and then back up again. Really annoying and I cannot figure out what is causing this problem. My settings are middle of the road in my opinion, no higher than in v4. I have ES Beta on but does not seem to matter if I turn it off. So far no CTD or running out of VM (1080Ti).
