Unplayable - Constant CTDs during flight for the past few months

yep, that was often the cause. But dont forget the issues with the Razer Software, just in case you have it installed ( I remember in special these game boost ).

But also note that a BSOD, which you reported too, are often hardware related or driver related. This would also match because you reported " nvwgf2umx_cfg.dll " too.
( testing whether you run into head issue, can you easy with setting a low max fps value )

And a note:

such as Google Photogrammetery,

it comes from Bing :wink:

In case you mean the google-maps-replacement, then uninstall it, clean your windows hostfile and use the default. This mod is a known trouble maker.
