I’d been having routine CTDs immediately or shortly after entering VR. Nothing worked for me in settings or workarounds. I gave up and started playing HLA (the best stand up VR experience possible) and it was crashing too. I checked the HLA forums and apparently this was related commonly to the swap or page file in windows.
I had disabled mine months ago after ‘optimising’ my pc. Turns out setting this back to auto in windows fixed my problem both in HLA and in MSFS - no CTDs at all. Maybe worth a look for others?
I’ve been having the same problem as you but my page file is already set to automatic. I never changed the default setting. It’s something else in my case.
But this is why I usually err on the side of caution when it comes to optimization laundry lists. Running through massive checklists of obscure windows settings and registry hacks found on forums very often has negative side effects. I usually sift through recommendations very carefully, googling each one extensively. The changes I’m less confident about get intense A-B testing, and if I can’t measure a difference, that setting usually gets left on default, even if someone else swears up and down it fixed all their problems.
