I didn't know the higher the FPS the lesser the stutters !

Less perceivable. They're probably still there, you just don't notice as much as the image is far more fluent. 

First of all, thanks a lot for all the quick and numerous replies – really appreciate the input from everyone!

I totally agree with the point that this is about squeezing out that last bit of performance, and maybe I just need to take a step back and actually enjoy the sim for what it is. That said, it’s still frustrating at times.

I’ll definitely try lowering the refresh rate as suggested. Right now, I’m getting a fairly stable 50 FPS, but the scenery often looks like trash – almost like I’m flying through Minecraft (okay, that’s exaggerated, but you get what I mean). It should be running smoothly with my setup, but these little microstutters are just strange.

Maybe someone else with a similar setup had the same issues and managed to fix them – would love to hear more about that.

What I’ll definitely take away from this is to try reducing the refresh rate to 50%.

I find it hard to believe that setting LOD and terrain to 200 will actually reduce stuttering, but I’ll give it a shot anyway.

At one point, I was even thinking it might require some BIOS tweaks.

The visuals really don’t look great at the moment either… but well, it is what it is.

I already have AutoFPS installed.

But honestly, I can really imagine the crappy servers being part of the problem too – among other things.

One quick question: would disabling Bing Maps help reduce the strain on the internet connection and maybe smooth things out a bit?

Thanks again for all the advice so far ✈️

built a completely new system specifically for MSFS2024 with the goal of running it in 4K

For a start raise your graphics settings a lot for a system like that!  I have everything on Ultra.  You card isn't doing enough work!

I used AutoFPS which puts my LOD over a thousand in many areas, never less than 400.  Object LOD to 200.

Wow, hard to believe, honestly — but hey, worst case, the PC crashes or bursts into flames, right? 😄

I’ll definitely give it a try right away.

Although I should mention: my GPU is usually sitting at 99% usage, and the CPU is around 30–35%.

Late Edit they could shut down the servers today and what do you got?

Let me answer XP, P3d or back to  FSX.

Did you just figure this out??

Alright, this is absolutely insane! I took a bit of advice from everyone and made the following changes: LOD 200, Auto FPS set to 30, everything on Ultra (except traffic and such) — and boom, what an incredible experience! I’m honestly blown away right now. The slight stutters are still there (but definitely improved), especially when looking out the side windows, but the sim just looks stunning now. You can’t have it all. It’s a beautiful sight. Thanks again, everyone!
What was the issue? No idea — and I don’t even care anymore! I’m just enjoying the new sim now 😄

You've summed it up:  your CPU is up to the task now but your GPU is nowhere near as potent in processing power nor VRAM as the 4090/5090 are so must dial back settings to deal with this then start saving for a big jump in GPU processing power.  While TLOD is especially CPU sensitive it also impacts GPU so yes start with very conservative TLOD using AutoFPS or my pref DynamicLOD Reset.   I should add I'm commenting from the perspective of someone who avoids Frame Generation wherever possible and its well-known artifacts, issues w/ second screens, etc.

Yeah, I still need to experiment a bit. The CPU is no longer in the red zone, now it’s more in the purple… but the sim looks great and runs really smooth.

 

However, I just had some really strange issues. When I switched to the external view, the camera suddenly started stuttering in a weird way—not the usual stuttering, hard to explain. After restarting MSFS, it was gone… but then it came back again when switching to external view. After a full PC reboot, everything was normal again.

 

Anyway, I’m done for today—that stuff is driving me crazy!

By the way, what exactly do you mean by AutoFPS and Frame Generation?

AutoFPS and DynamicLOD Reset are apps that dynamically change TLOD on the fly based on feet above ground level.  So on the ground you might drop that down to 100 or even to 50...but that primarily affects the CPU, and you're now clearly GPU-limited.  As you climb the apps increase TLOD/OLOD dynamically as your GPU can handle it.  You said it, pegged at 99%. 

So I guess what we all aim for are the right parts to support what we're after in the sims and within budget whatever that may be.  In your graphics menu you have the option of turning ON NVIDIA DLSS frame generation, which effectively doubles whatever the native frame rate is coming out of your total system as it's setup currently.  So if you can do a rock solid smooth 30FPS that gets doubled to 60FPS with the resultant smoothing out especially of fast-changing video imagery as with panning the virtual cockpit.  Since I was effectively CPU-limited most of the time I recently upgraded my CPU in order to NOT have to use frame generation because for me the artifacts, the alternating screen focus judder are not worth the doubled rate...provided I can maintain at least 50FPS-native + ~10% headroom over that when unlocked to cope with transient spikes in demand.  I can use TAA so have no issues with ghosted/smeared characters that happens with all DLSS methods.  So for sacrificing 10+FPS I get ultra-smooth stutter-free performance everywhere with best possible stable image quality at least for my hardware.

Thanks for your detailed post! I’ve found my sweet spot for now – at least as long as everything keeps running smoothly.

I reinstalled DLSS 4.0 and disabled Frame Generation again. I also stopped using AutoFPS, since I noticed that when the TLOD gets too low, raindrops stop showing up on the windshield. Without AutoFPS and Frame Gen, I’m now getting a steady 50 FPS with a great image, and so far absolutely zero stuttering.

So yeah, I’ve made a massive improvement overall.

I honestly never thought the CPU would be the limiting factor – but hey, I’ve learned a lot about how the CPU and GPU work together now.

There’s one last thing I’m planning to do:

I’ll find out which of my CPU threads are the strongest or act as the MainThread, and with Process Lasso I’ll bind MSFS 2024 only to those.

No way I’m letting the 9800X3D be the bottleneck! 😂

You are not working your graphics card enough.  Why have you set AutoFps so low at 30fps?

Have you got Frame Generation switched on? Is your monitor G-sync or Freesync?

You should be running at a minimum 60fps. With your system this will be easy with Frame Generation turned on.

I don't believe it is - you are seriously underperforming your system.  You need your graphics card doing more work.  No way should you be seeing degradation in graphics at a low LOD.  Your system is configured unbalanced - stop worrying about what core FS is on!

Yeah, I’ve realized now that my system actually runs much better with higher graphics settings. Frame Generation caused some issues for me, so I turned it off after testing it. I’ve also disabled the FPS limit. So far, everything is running great.

 

What graphics settings would you recommend increasing to put more load on the GPU?

Maybe this is the time to stop listening to advice on the forum.. 😊

I’m very satisfied 🙂 I’m fully enjoying the simulator experience.

Thanks again to everyone for your support.

I hope there are others out there with a similar setup who find this topic helpful!
