Short update from my situation.
I check again for BIOS Updates and as it turned out there was a new one from December 6th.
This one I did update and since then, I have had 5 successful starts where I could get on the runway. Had no time for a “longer” flight. But at least I am beyond the point it recently did CTD.
For your information my system specs are:
Intel(R) Core™ i9-14900K (32 CPUs)
ASUS ROG MAXIMUS Z790 HERO
64GB RAM Corsair Dominator
NVIDIA GeForce RTX 4090
Going to perform some test flights over the weekend and see if it still stays this way.
Good luck for all of you.
