Abnormally low FPS (10 FPS locked) + stutters/freezes approaching KBOS

[JEP795]

Not sure but found this thread which is exactly what is happening to me. Described it in detail there.

Coherent GT and Performance decreasing during flight

I have the same issue. Happens with a32nx and CRJ around the KATL area. I spawned there today and was flying around no issues, but I have noticed it happens when flying into Atlanta from an area that forces it to render. So I flew in from KGSP and boom there it was! Locked at 10 FPS limited by CoherentGTDraw. I’m wondering why it only happens in specific areas though
