After diagnosing my CTD issues these threads seem linked:
MSFS 2020 Crash in VR - HP Reverb G2 - Virtual Reality (VR) / General - Microsoft Flight Simulator Forums
Basically while in world page file usage has gone way up and physical ram usage has gone way down. As if someone called SetProcessWorkingSetSizeEx. My physical usage seems to lock right at 8GB while my commit was over 27GB. I still had ~50% free physical.
People that have slower HDDs are going to have way more stutters and frame dips as things are swapped in from the page file. I’m running a Gen4 Nvme drive so stutters are not as bad for me. Like everyone else I still have taking an overall FPS hit with 1.14.5.0. Hopefully tomorrows update will fix the low physical usage etc.
