Chakyash: By googling exception_access_violation (3221225477) you'll see a lot of people that had this kind of crash since game launch. And the most common solution I could find was to download MSI Afterburner and downclock your GPU just a bit even if you never overclocked. You can try that and see if it works for you.
Interestingly enough this seems to work when I down both the memory and core clock down -20, but only for an hour or 2 at most. A start, but still not a solution. Might just have to experiment some more with afterburner and find that key configuration.
That's weird!

I guess you have your answer there. Downclock it even more and increase the fans speeds in MSI Afterburner, then see how it goes. What is your 1080 Ti model and how old is it? You may need to change the thermal paste. Judging by these high temps, I would guess it's a blower-style Founder's Edition card. Not sure if it's that easy to change the thermal paste on those.

Maybe The Witcher 3 is more demanding on the GPU than the other games, especially with the HairWorks enabled. Personally, I wouldn't run the GPU over 82ºC for such long intervals. I'd rather have lower performance than high heat and fans noise. Try testing with FurMark too - it's probably the best GPU stress test and will heat up the card very quickly, but don't run it for too long.

The GPU is only 2 years old, I won it in an NVIDIA screenshot contest so it's just a reference model. After having spent a good while messing with afterburner I'm still getting a display driver crash. Sometimes it happens after 3 minutes, other times 20. I used DDU to completely clean out drivers, but after installing the latest drivers the crash still occurs.

I reinstalled the game today, ran it with graphics options all on low with no tweaking done in NVIDIA control panel, and the issue persists. Runnin outta ideas lads.

What about rolling back Windows updates if possible? Are you using Windows?

It's seems that the card is gimped in a way that is particularly apparent with respect to Witcher 3. Have you tried tinkering with hyperthreading and/or CPU core settings?

You could also try updating your bios, but I'm not sure if that's worth the risk.

Hard to say really. You have to test it yourself just to be sure. Fingers crossed!
