I think I maght have found a solution for freezes and crashes on Dx12 and ray tracing.
Problem
Game freezes for a few seconds, then 2-3 seconds black screen and gpu driver restarts. Sometimes even game crashes.
Fix
Delete cache folder, mine had almost 4 GB. I did it yesterday and I don’t have any problems since then. Still there are some fps drops but nothing serious.
EDIT: No, it’s still happening.
