Yes, although it seems worse with the A32NX than with stock planes.
The cause of the stutters seem to be coming from aircraft and vehicles at airports. Turn it to 0 and no stutters.
I just did some quick tests: all settings Low or medium zero stutters. With high a very occasional small stutter, and with ultra the stutters really began. So not sure if it is the same kind of stutters, as you said you have them even with everything low.
Sounds very similar. Sorry, what are your system specs?
Another update. I just tested with a C172 in the middle of nowhere. No stutters that I can see, at high settings.
So it does appear that it’s only happening in areas of denser scenery. Yet even in those denser areas, the FPS is fine…except for the stutters that occur. I would’ve thought the stutters would only occur in conjunction with poor FPS…?
And…even when sitting parked at, say, a New York City airport, although the devmode overlay shows green and 40FPS, it still has momentary dropouts where it goes “red” for the same stutter period, even when I’m just sitting there doing nothing and not moving.
So I guess that’s where it’s at right now…high FPS and no stutters in empty areas; but high FPS and stuttering in high-density areas. Would love to know why the stuttering is occurring even with high FPS 
Nope. It could be caused by assets loading or VRam being swapped in and out
Fair enough, and likely what’s happening in this case I guess. Is there any way to address this while keeping settings on high? Is it just new CPU/motherboard/GPU?
And here’s another weird thing. I create a flight in the A32NX and spawn on runway 4L as usual at Newark Airport. Devmode overlay shows green, about 35 FPS. I then go into settings and turn V-sync OFF, hit Apply and Save. Overlay immediately goes red, shows about 15 FPS now. OK, fair enough, I’ll change it back. I go back into settings, change V-sync back to ON, hit Apply and Save. And…no change in overlay, it stays red, 15 FPS.
How can this be??
Stutters generally occur if the cpu’s mainthread is bottleneckecked by the gpu. The best advice I can offer is to turn on dev mode and select show fps from the top of screen menu, it will probably show mainthread limited. What you then should do is set all graphics options ultra and and then start lowering TLOD until gpu limited starts taking over. If it doesn’t or TLOD is less than 100 then bump renderscale up a notch or two at a time until gpu limited is more prevelent. Should fps drop too much then lowering clouds to high is a good way to gain some back. I suggest you do all this in difficult scenery with default traffic settings, you can always adjust them later. I also suggest you use a default aircraft and no frame caps while you calibrate.
If you still get stuttering or freezes then your drive set up is then suspect, I highly recommend keeping all MSFS package files to their own drive which should also have it’s page file disabled (but do not disable all page files elsewhere, you still need 5-10GB somewhere on your system).
I5-10600K / 3070 / 32GB / 1TB SSD / 2k
I actually turned up the render scale to ensure that I’m primarily GPU limited, and that reduced the stutters quite a bit imho. On approach to an airport, I will still have them, but I can live with that

I’d say it shows an imbalanced system and as is often the case after any sim update the aircraft might need an update itself.
Monitor size is important too, anyone trying to run a 3080 or 90 on a single 1080p monitor is in for a real hard time, even a 4k one will probably need a renderscale bump.
Fair enough. I agree that I probably have an imbalanced system, which I purchased two years ago as a prebuilt PC when I knew about a thousand times less about PC components and system building than I do now 
So if you were me, and you had my system, and you wanted to upgrade components so FS2020 could run pretty much ultra settings at 4K, and money was not a huge object, what would you suggest? (my system specs are in first post of thread…using a 4K 85" Sony Bravia TV as a monitor).
Tbh your system specs look good especially if you can hit it’s 5.2GHz boost and the rtx 2070 Super is no slouch either but one thing that grabs me is your ram, it would be much better for you to run just 16GB at 3200 or more. IMO with dlss you should comfortably be all ultra (except maybe clouds) at 40-45+ fps. I assume all your drivers are up to date including the motherboard/chipset etc. so what about onboard sound? I generally hate Realtek and have mine disabled in bios preferring to use HDMI and a bluetooth dongle from my TV.
For the future just wait for the 7800x3D
Hmmmm. Yep, all drivers (mobo+chipset as well) are up to date as far as I’m aware (at least that’s what Armory Crate tells me). I use sound over HDMI going to my AV receiver via ARC.
As for the RAM, it’s overclocked to 3200 via XMP, since the Z490-V mobo doesn’t support that natively from what I can see.
But I’m with you–I feel like I should be getting better performance from my setup than I’m getting.
That’s for certain, PCIe4 could possibly help a little but I doubt that’s a big issue.
In my experience, this type of stutter is mostly related to scenery loading. This issue is significantly more pronounced with SU10 update and I think it may have to do with how 3rd party sceneries load up now! The Content.xml file is no longer used and so the prioritization is probably not happening properly, leading to these types of stutters! If you don’t have any sceneries installed, then that’s a different story. I get these, when I get close to sceneries. They are annoying and I hope Asobo finds a way to improve this. I did not have this issue before SU10.

And, I just double-checked, and my BIOS is indeed out of date–I thought that’d be updated through Armory Crate, but it’s a separate download. Here’s hoping the update I’m doing with it right now fixes the issue (wouldn’t that be something??). Will report back.

I can’t test this but that’s been an issue in the past which they did manage to fix eventually so there’s still hope then.
I had that too - have you raised the Tir5 priority to ‘high’ in the Windows ‘Task Manager’ ?
Do not use ‘Real Time’ but do raise it from ‘Normal’ to ‘High’ and there will be no lag or stutters.
You DO have to do this every time you start your PC though. So now before I open MSFS for the day I start Tir5 then open the Task manager and set the priority to High and confirm it - then close the Task Manager and open MSFS.
