Ok I'll keep that in mind, but I've had the game since mid-2021 with this same pc and never had issues.
I just did a graphic driver update and checked the integrity of the game files. I'll see if the issue persists.
Basically all comments here in this post are legit. Please check PSU, thermalpaste, component temps... worst case underclock/undervoltage your hardware and check again. Also DDU the drivers as well and clear the shader cache to be sure.
