CTD appears to be multiplayer only for me, in single player have yet to see a CTD with F14.
Edit: Also overclocked on processor (3.7->4.0ghz) and factory overclocked 2070
Edit2: Seems to be less populated multiplayer are fine, busy servers can result in CTD.
Edit3: Going to guess this is a DCS core memory leak issue, more noticeable on the F14 due to its higher memory use.
