You may be right. I had a flight today and the sim was stuttering again. Even worse, I got 2-3fps for a few minutes at crusing altitude. Though, I could swear yesterday was really smooth. One of the worst patches so far, for me at least.
Move your reder scale higher, try 120%, that should force the GPU to do more work masking any stutters. I am not sure why your CPU core is pegged at 100%. It should ideally have 5-10% free fore some kinda leeway. My system is almost the same as yours and my last core has 5-10% free most times.
I did, actually is at 130. Noticed that too.
Yesterday was smooth. Today is a disaster 
I disabled game mode, hags gsync. Still 100% on the last core. The only way to free up some cpu room on the last core is to indeed up the render scale to 140/150 or higher. But even then still have the problem with microstutters.
How on 
is this possible, what to do about it?
Wait for the next update and play FSX in the meantime. Works for me.

You might want to start by disabling HT first and compare.
You’re screenshot shows clearly the game task scheduler is pinning its main task, the game loop, to the HT CPU of the last core. IIRC when building my own task scheduler, literature was showing you’d rather spawn threads on main CPU core, not on the HT CPU core. In other words, spawn threads on CPU #0, #2, #4 etc…
In your case, CPU #15 is running the game loop and this is the HT CPU (the 2nd one) on the last core, and I believe this is not the optimal way. Otherwise, instead of disabling HT entirely, set process affinity to CPU 0,2,4,6,8,10,12,14
Ht.. process affinity… Useless struggling with all this..
The problem is the graphics engine of MSFS…

HT on ou off for me, doesn’t change anything.
there’s only Asobo to stop the stuttering

The way to not have one core at 100% is to limit the framerate.
If not limited, one of the CPU cores always 100%.
At least working with powerful graphics cards.
Another way is to reduce the LOD.
Have you try the Aerosoft CRJ 700 aircraft ? With this plane I don’t have any stutters even on complex airport when turning on taxiways.
MSFS2020 and stutters ? such an inseparable match…
Same for me. CRJ has a little less FPS but much less stutter. Unfortunately the plane is to complex for me at the moment. Lets hope that after the next update the standard planes get fixed the stutter when you are turning on the runway…
Of course… completely agree!
On my system this tip seem to work…move the render scale from 100 to 120, the frame rate dropped from 35-40 to 30-35 but with a lot less micro stutters. much better
thanks

Yes it does work. Also as nice side effect is that the image is now super sampled so also looks way better
Do tell how your stutters result in FS2020 being a game. Does this mean that my AMD system, having no stutters makes it a sim? Confused by this particular point stated in your rant. I feel you are comparing apples to oranges.
For what it’s worth, I’ve just posted this:

This render scale increasing from 100 to 120 does not
bring any improvements whatsoever in my system…

There’s not much you can do to fix the stutters. A sizeable portion of the cpu load is probably coming from flight model calculations, cockpit displays, gauges ect. Not much you can do about that.

and AI traffic, and animals grazing, and bumper to bumper traffic, and boats everywhere… etc.
All of which you can do something about. It is amazing the amount of load that can be released by dropping the sliders down on all the little things.
FYI, if immersion is a goal, why have a bunch of fictional airplanes and lunatic users doing barrel rolls over the airport in their A320? AI traffic is unnecessary and has no relation to reality. It is a filler. Multiplayer traffic is simply a distraction. Four aircraft all parked on the runway and you are on final. That’s real. If you want to release load on your CPU to try to get the smoothest, most immersive experience you can, then SHUT OFF multiplayer and AI traffic. Use Live Traffic and Group Only. That way the only a/c in the sky with you are the actual real world aircraft that are occupying the same airspace and the friends you want to fly with.
Remember… Take a load off, fly a while.
