VR-Suggestions for i9 10850, RTX 3070, HP Reverb G2

It seems I found my problem for the stutters and flickers. Disabling contact shadows was a big boost overall on smoothness. Even at KJFK and KLGA super smooth departures. Only had 2 sudden CtDs before CCC transition and the game was over. Don’t have any idea why the CtD happened. Any idea?
