Hey there,
as you all know there is a GPU melting issue that’s plaguing this particular game.
This bug triggers at irregular intervals (5 to 30 mins) (even when just standing / moving around in town in act 1).
It’s only happening in this particular game, thus implying it’s an engine related bug.
When it triggers the following SUDDEN CHANGES happen:
GPU Core Clock jumps from 1000 MHz to ~1980 MHz INSTANTLY.
GPU temperature rises from “chill” 50°C to 65°C.
Fan speed ramps up to loud 50% (from silent 30%).
GPU Load drops from 85% to ~50% (paradoxically).
Voltage goes from 0.7V to 1.0V and stays there.
No matter what you do AFTER this bug happens, you cannot fix it.
No graphics changes, no legacy-gfx-switch (legacy mode puts both clocks down to 200 and 120 MHz respectively, but leaving sets them back to ~2000 MHz),
no save & exit and new game, nothing helps except restarting the entire game client.
GPU utilities like RTSS or Afterburner stop working when this happens (indicating that it could also be a driver issue).
Tested with:
GPU: GeForce GTX 1070.
OS: latest Windows 10 21H1.
Driver: 472.12 (d2r ready driver).
NV CPL: 60 FPS lock & VSYNC on.
NO INGAME SETTINGS WHATSOEVER (quality, resolution, sharpness, windowed/fullscreen, etc.) have ANY effect on this issue.
The only thing that resolves it is a hard restart of the .exe.
I’m relatively certain that people that have GPU heat issues are experiencing this exact bug.
Want to check it for yourself?
Start monitoring your GPU temperature when starting a new game, sit in town or move around,
after some time you’ll notice a sudden change in the graphs.
