@viem It's a 550w corsair.
But I doubt it is PSU related, for eg RDR2 is significantly more demanding on my pc, but I never had something similar occurring.
Doubt though is not a certainty.
My point is that I never had anything like that happening on any other game, and I am constantly monitoring my temperatures, have the latest GPU drivers, etc.
Am not excluding hardware issues since I am a pc veteran and dealt with similar situations for years, my question was made so that I can have the community's feedback and learn if anyone else is experiencing similar issues.
