RTX 2070 Super, 1440, all on max (Very High and Ultra).
I’ve capped FPS to 60 and set V Sync for both: in game and Nvidia panel for D2R
First run:
Temp: around 58C maxing on 60C and GPU Power around 190-200W
then I’ve updated Nvidia drivers + PC restart and now:
temp: around 43C maxing on 45 and GPU Power: 90-100W
So my advise: cap FPS to 60 + V sync and update the drivers.
