I installed the newest Version 2 days ago and flown 2 1/2 hrs in the TBM today without a CTD.
But I guess I noticed the FPS drop during my descent through a few layers of cloud. I took the outside view and during turning around the aircraft it was stuttering much more than i expected. (Have a 2060s only and playing in High with some ultra sidekicks)
I had updated my Nvidia drives in Dec – and then started to get CTD after a few hours of flying.
After seeing your post, went back to 457.30 and not a CTD since. left sim running all night, flying, and it was still running fine, at same FPS after 8 hours …
