Windows 11/latest/32GB RAM, Nvidia 4070 / 12GB RAM
FYI my constant crashing seems to be ** fixed** by simply limiting FPS down to 60 or below, leaving VSYNC on. Setting the graphics options to High or Extreme had no impact. At first I thought it was a DirectX 12 issue and was playing on Vulcan - but switching back to DirectX 12 was stable too. All having to do with lowering FPS.
Most of the worst crashing seemed to happen while I was referring to the guide in game (G). I was following posts on Steam Community attempting to fix and locking FPS was a suggestion there too.
