This latest information sounds realistic: thank you for your diligence.
Might one ask you to edit the thread title and first post to make the true state of affairs clear please? If not, a lot of people will latch onto the first bits and believe that is the full story, while that is totally not the case.
I managed to overclock it by 100MHz
Lets see how much difference it made xD
Before overclock I got 51.6 FPS on High-End.
I now get 54.9
So that gave me a 3fps difference 
haha.
So 100mhz makes a slight difference.
This is the only think I need to upgrade, my GPU, unfortunately zero stock everywhere.
Im the same! 
I want a 3080!
Maybe we will be lucky to buy the new 4080 when it will be available, I hope this crypto s***t will settle down.
Even without the crypto market there would be GPU Shortages.
In Short Nvidia failed to estimate how popular the 3000 Series was going to be, and Coronavirus hasnt helped.
They reckon it could take a year or two for it to recover
Standard LSGG, 12:00 Clear Sky, Runway 04, A320 neo vanilla, all settings High (including glass cockpit refresh rate)
My System:
AMD Ryzen 5 5600X
MSI GeForce GTX 1070 ARMOR 8G OC
64GB RAM G.Skill Ripjaws V
GIGABYTE B550 Gaming X V2
1 x Samsung SSD 840 PRO Series 120GB (for Windows 10 Pro)
2 x SSD ADATA XPG Gammix S11 Pro 2 TB NVMe (for Games)
AMD Ryzen5 5600x or Intel Core i9 10900KF? For a gaming computer, I clearly prefer the Ryzen. The Intel is only slightly faster from 4 cores upwards, which is irrelevant for most games. And if the MFS uses all cores at some point, then both processors are underpowered anyway. The Intel has higher watts (more power consumption and heat dissipation).
You can see in the picture how little the cores are being used. I haven’t overclocked anything, and I won’t. There are still some reserves. So the statement “This game performs worse on Ryzen” above is wrong. Please revise. In my opinion, the two processors are equivalent (for gaming). I think with the appropriate graphics card I would also get over 60 FpS. But I have to get one first :(. I am currently limited to GPU.
When I run MSFS on 1 core, startup takes between 30 and 35 minutes. Flying was impossible with 1 core because MSFS froze. I killed it after 45 minutes. Not sure how MSFS works only on one core.
It doesn’t. Core 0 has the heaviest load to be sure, but the balance is spread evenly across the remaining cores.
My setup uses a Ryzen 5 3600 on an X570 mainboard, with 32GB 3200 ram and a 1TB NVMe PCIe Gen 4 SSD. The OS (Win 10 Build 1909) and MSFS reside on the same partition.
Post-patch I have seen frame rates in the mid seventies in the Carenado Mooney, and not lower than mid-thirties around KSFO deep in Class B airspace.
GPU is an RX 5700XT.
MSFS works on all cores. But the ‘mainthread’ is only assigned to 1 core.
Always the same old discussions. Why don’t anyone researching before posting?
Many posts in this forum exists, several youtubers pointed out that topic…
Ryzen 3xxx behind the IPC of Intels 9xxx or 10xxx
Ryzen 5xxx better in Terms of IPC.
You completely ignore differences in RAM configurations and sometimes big issues with settings in your BIOS.
Believe me, my Ryzen 5600x doesn’t lack behind a 10900k… 
All games perform worse on Ryzen. End of story. No need to keep having this discussion.
Well, its very clear you dont read the last tech news, do you?
I call bollox on that one.
Even though this test wasn’t done in identical condition(or maybe it has) but I tend to strongly agree with Yetty5997. I a have rift s, RYZEN 5600x, 32GB 3200MHz RAM, msfs is on ultrafast m.2 and RTX 2080 super OC. CPU never goes over 40% on any single core nor as a whole CPU and GPU never goes above 72%. MSFS behaves the same if everything is on ultra or on low. Rendering is 100% with TAA, LOD is 100 for both, AO is off! What can I to to make the game use all of the available resources
p.s. I even went to the extent that I have clean Windows 10 installation just dedicated to MSFS 2020 and still no luck,
