Pure speculation here, but check your hotspot / memory junction temperatures (you can do this in HwInfo). See if they differ wildly from your other games.
Different games have different load profiles, no "100% usage" is the same (see for example what Furmark does vs. What a normal game does), but your issue sounds extreme.
All settings are stock, right? No OC, undervolt or any modifications? Hit that "restore to stock" button in Afterburner to be sure :)
Hot spot hit 97 C in Outlaws but my max temp was 80, an improvement from yesterday. Maybe it was something in the prologue + higher RTX lighting settings?
