If you have to much stutters at an airport or at approach then tune down your object LOD setting. Less objects together .

Also you could try:

MSFS : FG on / VSync Off 

NVCP : FPS capped at 56-58 (for a 60 hertz monitor)

Sure, assume default KSEA. Any particular settings? Normally run mostly maxed out, FG ON capped at 90FPS and 1440p but set DLDSR resolution to 4K in my last one, to push the GPU even further.

Yep, default. Settings are ultra with TLOD at 300.

Can actually confirm, without frame generation, I'm seeing similar low performance at KSEA. That said, it's partially tied to Terrain Level of Detail. Simply bumping it down to 200 increases performance and resolves a lot of stutters. Turning on Frame Generation with 200, makes it very smooth again. 300 is a very high setting.

There's something definitely wrong then, even at 200 I can't get over 22 FPS and the CPU bar is completely red.

Got a new motherboard (Asus ROG B650E-E) and a 7950X3D today just to test it. Did a clean Windows install and installed all the corresponding drivers.

Surprise surprise, exact same thing is happening. GPU is fine, CPU is pegged and frametimes go through the roof. Compared directly to some benchmarks I found on YT and my performance is significantly worse using the exact same settings.

Don’t know what to say 😶

Your new cpu and motherboard shouldn’t affect performance, unless the older ones were defective (it’s even debatable that the 7800x3d will perform better because its single ccd has 3d cache vs the 7950x3d which has a second ccd without 3d cache).

I have no idea what’s wrong on your end. Can you please record new tests using Riva Tuner to show how’s your hardware behaving.

I'm happy to be corrected, but I'm pretty sure since AAU 1 the above doesn't have any effect with FG anymore (not if you're using V-SYNC anyway to avoid tearing). It certainty doesn't on my system.

Did you wipe out the SSD completely and redownload MSFS too?

Make sure with the 7950X3D to use Process Lasso or something similar, to set your cores to the ones with 3D cache on it for MSFS.

Yes, it's a fully clean install.

Tried copying the settings as well as I could. Not only are my FPS lower, it's also very stuttery compared to the smoothness of both the comparisons.

Will check, but

Oops, sent that too early. I think it should be performing better without tweaking anything still.

Things I noticed:

1 - FPS shown on Riva Tuner were supposed to be higher than those from the internal counter. The reason is the internal counter doesn't count the frames created exclusively on the GPU through frame generator. In your case, Riva tuner is showing lower FPS. 
2 - Try turning off Vsync. AFAIK frame generator doesn't work well with frame generator.
3 - As the internal frame counter only count half of the frames (when FG is on) I'd say your FPS are ok. What's killing your experience is because it is really stuttery. I would say the Vsync must be the cause for those stutters.
