Hard crashes or blue screens from playing flight?

My setup:

Geforce RTX 2070
Intel i9-9900k
16 GB ram
1080p 165hz with AMD freesync

Been waiting so long to play this but after installing I see optimization is pretty poor for PC. I obviously have no issues running the game on ultra, but fps is inconsistent, and after a while game suffers performance-wise. Just wondering if anyone has been having this issue, I’ve tweaked the settings a million times and I know everything I have is functioning well and up to date. After about 30 minutes the game will randomly crash and with it my PC. Overall fun game, Halo just might be back.

Post your rigs too and give me your feedback as well!
