I have a very stable system and performance has been great throughout this period where others report bad stutters. Nonetheless, I’ve had CTDs, either loading into Flight or exiting the Sim, so I’m not claiming immunity from this phenomenon.
CTDs, unless they represent an excessive amount of one’s activity in the sim (and that would vary across appetites and expectations), are a fact of life with applications in general. Programs crash or Abend.
What’s difficult to troubleshoot is because of the variety of hardware and software configurations in the real-world. There’s just too wide a variety to effectively test a full spectrum of operating conditions. It would be one thing if MS could impose a hardware reference that’s very locked down (i.e., iPhone or Google Pixel) and then testing could be very focused because of small sample variation. That ain’t gonna happen in Windows land.
