I too am experiencing this issue. I’m worried about damaging my PC. I’ve capped my frame rates, and made all the adjustments recommended to avoid damaging my GPU, but it still deadlocks. No defined moment either. I can happen as easily in combat as it can just walking about.
You should be worried. I had this issue once and i stopped playing immediately, youre lucky that your GPU hasnt died yet if you crashed like this multiple times.
