I used to watch my cores and wonder what was actually happening too. I do set affinity off on my Core 0
for flightsim.exe so windows has some working space. I believe it has helped but not sure as when I started doing that was after 2nd update, but I will say I have had no more CTD’s at any time aside from drone camera usage(fixed now I think) and flight plan manipulation in game (fixed now I think).
My specs are very similar to yours
