Well, that’s interesting.
Maybe the card is throttling due to not having enough demand…
There is a setting for this, in the nvidia control panel.
Power Management Mode. Try setting this to maximum performance. Then put your graphics back to where you normally run them.
I currently have a 3070 Ti, coupled to a 12900k on 32GB of DDR5, with a high speed NVME.
Now, I’m not running my power management at that setting, but I am running the game at 1440p at full ultra with the high res packs, at 100FPS without any FPS dips, no stutter, no lag, nothing, and average temps in the low to mid 60c’s on the hotspot, and lower on the GPU. It may be that the load is heavy enough that it doesn’t have an issue, but if you have a higher card than I do, it may actually be having this weird problem of shutting itself down and leading to a crash.
There were instances of this with some other games before, and a few reports on the forums, but not enough to worry about.
But its something to try.
I will be picking up a 4080 Super next week. Going to see if my luck changes then.
I hate linking this, but it has all my current game settings. And yes, they haven’t changed from when this post was done:
