THIS IS AN OLD POST. NEW ONE HERE

Hey!
Got my Zotac RTX 3080 "Gaming" yesterday, which has replaced my 1080 Ti.
Now, I have a problem which I have failed to find an answer to searching a good while.
While playing DCS in VR (which is what I use to test the card) and so far the only game I've really sat down to play, I run into this weird behavior of the card. It takes the card a while for it to start misbehaving, sometimes 30 minutes, sometimes 2 hours.
So what is it? Well...
Suddenly, the FPS will drop by 1/2 or 2/3 (locked in steps by VR), from 45 (with the odd jump to 90 and other normal fluctuations) to 15.
At the same time, as you see from the image, the GPU is shooting to 100%, and the Power usage (W) drops by an equal amount.
I would normally expect the W to go hand in hand with the GPU %, but it doesn't. And the behavior is completely random; I'm not doing anything special, or going to a "dense" place. It can happen with me sitting there not doing anything.
Today when this happened, I tried bumping up the fans to see if it was correlated with temperatures, but nope (I have marked this with yellow lines in the image).
You can also disregard when the graph shows 0 fps as that's when I have the game in the background, those moments are "normal".
I have mounted the card with the included two "2x6 to 1x8" power cables, and my PSU is a Corsair 750W.
Does anyone have a clue as to what this is? I wish to solve it within this weekend (before Tuesday) so I can decide to keep or return the card.
You can see the image here (I wasn't able to add it to the post)

Edit 2:
So I've now stressed the card running MSI Kombustor for 15 min, and it's stressing the card more than DCS in VR with higher average GPU % load and much higher average Power (W) usage.
And it's doing it without a hiccup.
I've also started OBS and some other tools simultaneously to push the card even further, again without any problems.
Here's an image of this test
Edit 1:
- no this is not normal behavior from DCS. I have never seen anyone reporting this before and I have never seen anything like it. The forums are void of this problem
Anyone? Help is MUCH appreciated.

Question - FPS and Power drops, as GPU peaks..?
