I just did the EGLC > LFBO > GMMX flight again with which I had the CTD.
I increased the virtual memory from 32 to 48GB
Like yesterday, I had an image that got stuck with black frames when I moved my head over an area of England.
On the other hand, when I passed over the zone, in France, where I had had the CTD, everything went well.
About 5 minutes from GMMX the G2 screen went black and the GPU fans stopped. I thought about CTD, but actually no, MSFS was still running in 2D.
Before relaunching VR, I saw in Event Viewer that this switch from VR to 2D was caused by a crash of RTSS.exe (RivaTuner) that I thought I uninstalled.
So I relaunched the VR flight, until landing, i.e. after about 5 hours of flight.
I wanted to taxi to the airport, and there …
50 meters before arriving at the foot of the footbridge, the CTD erreur VCRUNTIME140.dll
What can we say, apart from 50 meters away, everything could have been positive. But hey 5 hours is already not bad.
