I flew Barcelona in the DA40 TDI @ 1200 ft.
Settings and Dev Mode report below.
As a reminder: 5800X3D, RTX 3090 Ti FTW
I have 64GB RAM. 18GB are used as a RAM disk that I use for Rolling Cache.
‘Limited by’ was flashing between ‘Main Thread’ and ‘GPU’ - which I what want. I could increase some of the CPU settings, since my GPU load is maxed out.
Why use Safe Mode when clearing the cache?
Is it to disable the nVidia driver completely?
Is that better than turning off Shader Cache in NvCP and doing a normal restart before deleting the cache files/folders.
Just curious. You are running the sim with no AI traffic in the sky?
Yes. All traffic is OFF.
I’m trying to establish a set of baseline benchmark conditions that give me excellent performance with balanced Main Thread/GPU limits so we can see OP’s performance with only moderately high graphics settings. Same plane, same scenery, and If OP sets his NvCP and General Settings the same, we can dive deeper into what’s going on if his performance isn’t at least 75% of mine.
He has a better GPU, and a comparable CPU - although I do think my X3D CPU has an advantage. As I stated earlier in this thread, I went from a 5800X to a 5800X3D and saw a definite 15-20% improvement. On-die L3 cache is king. And the sim code is definitely NOT taking advantage of more cores. Maybe it will in FS2024 - it’s what we’ve been told. If that’s the case, then maybe his 12-core 5900X (with its higher clock speed) will outperform my 5800X3D.
So if I see 83 FPS / 12ms in the DA40 over Barcelona, I would hope he would see at least 65 FPS / 15ms. But he needs to have the exact same NvCP and General Settings, and continue testing the DA40 over Barcelona for the comparison to be meaningful.

Ah … I see now 
Ten out of ten here for your continued efforts in helping a fellow simer. It’s really nice to see

FYI The 5800x3d pairs well with the 4080super. That’s basically my specs. Solid performance even with FG off. Like you said
Yes the 7800x3d will give you more frames but the 4080super is fully utilized with the 5800x3d and it outperforms the 5900x in this game.
I think you underestimate how capable the 5800x3d is
“The elephant in the room”
FS2020 behaves very erretically. From one hour to another, performance (stuttering, stutterfree, banding etc) could change a LOT! Things that might help in FS (Ive tried myself):
Sync the clock in windows and see that it syncs (no red no sync message).
Don’t use Reflex! (works for me anyway)
Change to another server. Could give rediculus difference!
Try BOTH vsync in NCP (or AMD similar) AND in game. (yeah weird, but could make a difference)
10Gb shader cache (after clearing it with procedure: turn it off, reboot, check Appdata folders for cachefiles (could be find on youtube). THEN set to 10gb and reboot.
DX11 = better performance in the sky
DX12 = bvetter performance on ground / close to ground (for me)
3060 Ti + 5600X which I guess is kind of low-mid system for FS?
I hope you get on with better performance soon.
Not at all - it’s an extremely capable cpu especially with the sim and used by many. My point was the 5900x is just as capable if not more in every aspect EXCEPT the extra performance the 3d-cache provides the 5800x3d. In my opinion, the 3d-cache is not going to make the 5800x3d 20% better because some of the benefit the 3d-cache brings to the table is offset by the higher clock speed of the 5900x cores. So again, the 5800x3d will be better, but not 20% better.

Thank you, what do you think about overclocking cpu then, I have pretty good water cooling on cpu, so it should be able to handle slight OC, but would that mean a lot in our MSFS case? I have no idea…
I really appreciate your help. So now I doubled checked the settings in MSFS, I think I also applied all of suggested changes. Cleared this cache too. And here it is the result from DA40 in Barcelona. Please remember I am playing it on 3 monitors at 2560x1440 each, so should I run it on 1 monitor at your resolution to have proper comparison?
The 5900x will overclock/underclock nicely and you’ll get an additional 3-4 fps in MSFS but more importantly it will help out with cpu hungary add-ons like FSLTL.
The key for MSFS is to focus on getting the 5900x sustained boost rate high, not peak boost rate as the peak boost only lasts for a split second. Each motherboard is a little different and each 5900x chip is a little different on what OC/UC it can achieve. My recommendation is to turn on PBO if you haven’t already and set the limits to “Motherboard Limit”. Max boost clock override should be set at no more than .75GHz. Then optimize the underclocks of each core starting at about -10 and change a very small set at a time to dial each one in.
The key to this approach is that the lower heat enabled by the underclocks will allow the cores to boost longer and this will ultimately benefit the MSFS “mainthread”. You’re not going to get a max boost of 5.4Ghz for a split second however you should be able to achieve sustained boosting of around 4.9GHz with a couple of cores.
Youtube is your friend on how to OC/underclock the 5900x. This is one that I liked:

It would be interesting to see your test with one monitor.
I have a 4K monitor for the sim, and a 2K monitor for other programs.
Also, I’m puzzled that your Render is reported as 1707x960 with the settings I listed. I would expect 2560x1440. Maybe that has something to do with the 3 monitors running the sim?
I do see that you are running DX11, while I’m running DX12 / DLSS / Quality, so your settings don’t quite match mine.
Having a current DLSS version is helpful, even if you are using TAA.

Simply not true. I had a 5900x, sold it and got a 5800X3D and it’s a huge difference. There are several benchmarks online, but it can be as much as 50% in 1080p.
There is a reason why the 5800X3D has been more expensive than the 5900X for a long time.
Yes, you are right, it was snapped before restart, so it was still dx11 - sorry about that. Thank you for DLSS swapper hint, I can confirm it’s been done from 2.5 to 3.60. Removed rendering of additional screens and did max resolution at 2560x1440 - one screen only. It’s around 60fps, jumping from red to green… pls see attached
render size stil the same with 1 screen…
That’s very interesting with this OC/UC to sustain boost. I gotta look deeper into it, cause I only managed to turn PBO on and off without further settings and that was my whole experience with overclocking my setup - seen no difference, wasn’t bothering but maybe I should have given it a deeper look…
Your Render Scaling needs to be at 100…
