Check the reply above. I know this is with frame generation on, it’s still low FPS and stutters for me using it.

Also, not the FPS topic, but what’s the deal with the photogrammetry popping in and out like this? Terrain LOD is at 400 and object LOD at 200 in this clip, and the popping is extremely noticeable and distracting. Is it only an issue for me or does it happen to everyone? My internet connection is 1 gigabit up and down so I doubt it’s related to that.

Theory isn’t proof.
There is a user here on the forum who had a 7950X3D first and bought a 7800X3D at release and tested it.
He had worse performance with the 7800 and sold it and retained the 7950.
See:
I’m not experiencing stutters, other than the occasional as I fly into a heavily detailed AP region and/or with 3rd party airports as the detail is loaded in. I don’t really get stutters on the ground, but I do see my FPS tank pretty signifcantly.
FSLTL is robbing me of 10-15 FPS and that is with the radius set to 10 KM! I have not found a way to get FSLTL to not do this. I’ve messed with its settings and had little to no results in improvement.
If I turn FSLTL off, I can get near 60 FPS on the ground. Panning around still really hurts.
Again, I’m running at 4K.

Yeah there’s something weird with FSLTL injector. I get a fairly large performance hit depending on where in the world I load in. With it off, TLOD 400 isn’t really a problem.

Let me clarify here that this is in heavily populated areas at 3rd party airports, with live weather in high-fidelity aircraft like PMDG 737 or Just Flight BAe 146 and the AAU2 versions of the 747 and 787.
In rural airports with GA, it’s an entirely different level of performance.

Are you using FSUIPC? Older versions of it can apperently cause issues. I also believe MobiFlight can install it automatically, if you are using that, but not thinking you are using Fsuipc. https://forums.flightsimulator.com/t/fsuipc-introduces-microstutters-every-second-su12beta/578005

Nope, never used either of those programs.
I have the same CPU/GPU on default Ultra settings using ultrawide 3440x1440 (default also gives me 200 TLOD and 200 LOD)
After trying what felt like everything I was getting some micro stutters especially around taxi and stutter on takeoff, with random stutters here and there.
What fixed it for me is what peeps say about making the GPU more busy and CPU less busy if needed, forcing the GPU to take longer which means the 7800X3D can keep up.
From sim graphics options I set render scaling to 120 from 100. Now the GPU is on 99% and after a couple hours of testing I haven’t had any stuttering, finally I feel my rig is performing how it should be.
As a bonus, turn TLOD to 150 to reduce the latency even further. Honestly it doesn’t even need to be at 200 so you can see a tree appear from 10 miles away… I don’t even notice any difference graphically but a big difference in performance.
If that doesn’t work, regardless of your cinbench score I’d say you have a duff chip (unless something badly misconfigured in BIOS)
I have the render scaling at 130 as well, so that should be fine.
About the chip, even though it didn’t make much sense, I got another one today just to confirm, and I still have the same issues in MSFS.
Don’t know what else to try, I feel like I’ve done everything possible at this point lol
Just to check, what TLOD were you running here?
I exchanged my chip for another one just to check, and with Ultra settings, 300 TLOD and traffic this is what it looks like now, not even 20 FPS and the CPU is completely pegged.
Standard Ultra settings, so TLOD 200.
20 fps and stuttering are hard to explain with your config, so many things to check…
There are red spikes and inconsistent frametimes for the GPU too, which is even more strange.
Try to monitor CPU and GPU frequencies and temperatures with HWInfo64 and background tasks with task manager during these tests.
I would also reset BIOS settings to default for now (no EXPO).
There must be something wrong “under the hood”, this is not a MSFS problem.

Yeah for sure, it’s just really weird because I feel like I’ve tried everything at this point and haven’t been able to diagnose what the problem is.
I’ve tried EXPO on and off but it didn’t fix anything, also monitoring with HWInfo everything is working fine. Temps are good too (although the CPU does get really hot when benchmarking). The PC is performing well everywhere else, it’s only MSFS where it struggles. This is gonna drive me mad

OK well I guess that rules out your chip as the problem.
With Ultra preset , render scale enabled to give the GPU more to do, and with TLOD + LOD set to the default of 200, it should be nice and smooth, regardless of weather and/or AI traffic…
As mentioned even your GPU when monitored is making some red spikes. Got to be a setup issue somewhere or something not right in the BIOS.
Stupid question but I assume you’re using a DP 1.4 and not HDMI cable? Worth ruling out.
A good idea to reset the BIOS from above, and also reset the GPU to base settings.
What refresh rate are you running your monitor on?
Any overlays running? Geforce Experience? AMD Adrenalin? Steam? Originally I had them all running but after troubleshooting and doing a clean W11 install I made sure I didn’t reinstall them, same with iCUE software.
Have you tested any other demanding games?
Any USB hubs, peripherals or printers connected that might be conflicting? If yes disconnect the lot and retest. Might be worth testing a standard mouse/keyboard if possible to rule that out too
I cleared CMOS, may as well reset it properly lol. No changes.
Yes, I’m using a DP cable and it’s connected to the GPU properly. I’m running the monitor at 100hz, tried it with another monitor at 120hz too.
No overlays or programs running, not even iCUE.
I haven’t tested any other demanding games, but I’ve done different benchmarks and all had decent results.
Also tried disconnecting everything, checked with older mouse and keyboards, but it didn’t make a difference either.
I just scanned the whole thread and don’t think I saw this asked or posted.
What are you using for a power supply?
Corsair RM850.
Dunno if any of this applies:
Was it a brand new machine?
I’m wondering if Windows is doing some indexing or something in the background whilst you’re attempting to game. It wouldn’t be the first time that’s happened.
Hey, here is something you might want to look into and I’m willing to bet it’s what might be causing your issue. Well, hopefully.
Make sure you don’t have the AMD Graphics card drivers installed or even the iGPU drivers. In fact, make sure you don’t have Adrenaline or any AMD graphics stuff installed.
If you did have this installed, then firstly, you will need to uninstall it using AMD’s clean up utility.
https://www.amd.com/en/support/kb/faq/gpu-601
Use this and only this. It will only uninstall any AMD graphics drivers which you don’t need since you using Nvidia card. Follow the instruction from AMD link provided. After you have uninstalled it, you then need to reinstall Nvidia graphics drivers. Make sure you do a clean install of the Nvidia drivers.
This should hopefully be your fix.
I recall I once had this same issue where I would be locked at around 24 fps and the culprit was the AMD graphics drivers which had somehow been installed while installing chipset drivers.
Again, make sure you uninstall AMD graphics drivers and THEN reinstall Nvidia graphics drivers. You have to reinstall Nvidia drivers otherwise you will still have same issue.
After I did this, my 7950X3D was back to BEAST mode at around 85-100 fps.
Also, I would recommend getting at least 1000W power supply for that setup.
Let me know how it goes.

I’m using one of the low end Gigabyte cards so I don’t think this applies, the 7800X3D isn’t that heavy of a chip too.
