Hello dudes, had the same issue yesterday. Not sure if it helps, but we tried troubleshoot it with my friend who has no problems at his conf. First, i ran in dx 11 with kinda old nvidia drivers. Got freezing. Then i've tried running in dx12. Same. After googling a bit, I've turned off nvidia overlay stuff. Discord overlay were off. Still got freezes. Finally I've updated my graphics drivers. At first it seemed to be ok, played like 2 minutes in. Then got frozen screen again. Stopped trying after that. 😢
conf is 7600k, 1660 Ti. Driver Version: 31.0.15.2647
BTW, im not sure, but most of my freezes occurred when i were actively moving, like slide jumping or used grapple on path. BUT against that, i've froze while scoping too so... Maybe its a game where you just jump half of the playtime 😃

EDIT: I see some pattern with the reports, the better graphics you have, the more time it takes before it's freezing. Maybe it has something with GPU mem or something idk.
