By working means it eliminates stutters/ctds?

Yes, smooth flying.

Please understand I’m trying to help, but It’s clear from that post you’re not fully understanding what it is you’re doing vs the indented outcome, as turning down settings is the last thing you should be doing. Think about it. Why, if your GPU is UNDER-utilised, are you turning settings down? In doing so you are exacerbating the problem and making things a whole lot worse.

You are making your CPU the bottleneck and unless you have a very strong CPU that will always end in tears. ā€˜My GPU is only at 20% and my CPU is constantly pegged at 80-100%’. You’ve even said it yourself.

I don’t know what your GPU/CPU combo is, but I would start by turning your graphics settings as high as they will go and work from there.If you understand how to set simulators up correctly for modern hardware FS24 is just fine but it really helps to understand that turning settings down does not automatically mean better fps, and in many games hasn’t for years.

Finally, FS is a demanding game. It has always been like this. I was waiting for the 5000 series of GPU’s to upgrade my system, and when I saw how poor they were (5090 being the exception but ludicrously priced) I bought a system with a 4090. Unless you don’t intend to play in 4K, any non-5090 50series card doesn’t really cut the mustard, and 16GB of VRAM simply isn’t enough to run this sim satisfactorily in 4K with all bells and whistles turned on. To be fair, however, SU3 seems to be much much better in this regard. I know the min specs say what they say, but they’re largely a work of fiction. Judge them on what they don’t say rather than what they do, and they make no mention of resolution or level of graphics fidelity.

Happy to help but we need;

  • Your CPU
  • Your GPU
  • Your RAM
  • What resolution you play at
  • The refresh rate of your monitor

Thanks for the reply, and I do appreciate that you’re trying to help. I’m not trying to push back for the sake of it, but rather explain what I’m seeing on my end and why I’ve done what I’ve done.

You’re absolutely right that turning settings down can sometimes make things worse, and that’s exactly what I’ve found frustrating. I get that under-utilised GPUs often mean the sim is CPU-bound, and in theory, increasing settings (especially GPU-bound ones like render scaling, terrain/objects LOD, ambient occlusion, and shadows) can help shift the load back to the GPU. But in my case, doing that hasn’t really helped much, the GPU still sits idle, and the CPU still gets slammed.

Here are my specs:

  • CPU: Intel i7-10700K @5.0 ghz
  • GPU: NVIDIA RTX 3090 24GB
  • RAM: 64GB DDR4 @ 3600MHz
  • Resolution: 2560x1440
  • Monitor: 60Hz G-Sync (Locked)

I’m not even on 4K, or at 1440p, I run the sim in window mode at 1080p and despite the RTX 3090 being a rubbish of a card, I’m constantly seeing 20–40% GPU usage in many scenarios, while my CPU is pegged at 80–100%. This happens especially in dense areas or non-dense areas, or when using complex aircraft like the Fenix A320 or A350.

Just to clarify, I’m not running everything on Ultra, not even close. Even though the sim’s recommended preset defaults to Ultra across the board, I’ve manually adjusted things to be more balanced.

And the thing is, I do get a solid 60 FPS in the C172**, so it’s not like performance is broken across the board. (FPS, I do not care as long as I get 60, it’s a SIM) But once I switch to something more demanding, like the Fenix A320 or Inibuilds, especially at medium airports, that’s when the issues begin.

Even if I drop FSR3 or DLSS entirely and just cap at 30 FPS, the performance doesn’t improve, and the CPU usage remains consistently high, often hitting 100%. Meanwhile, GPU usage swings wildly from as low as 20% to occasionally 80%, depending on what’s happening.

I’ve tested this with everything on Ultra, with mixed Medium/High, and even tried turning some visuals down low, and no matter what, the CPU is always the limiting factor. Even when I try to reduce load through settings, it makes no difference. It’s like the CPU is locked in a fight it can’t win, and the GPU is just along for the ride.

For context, this is happening on Beta 3, so I’m fully up to date. Just trying to figure out if there’s something I’m missing, because right now, whatever I do, the sim seems to lean heavily on the CPU, and doesn’t fully utilize the GPU unless I’m flying something lightweight in an empty area.

What’s especially odd is that in MSFS 2020, I don’t see this same imbalance. It’s still CPU-heavy, of course, yet 2020 doesn’t eat my CPU, but the GPU gets utilised properly, and I get smoother, more consistent performance. In 2024, it’s like the sim just refuses to give the GPU anything meaningful to do, even on Ultra settings.

I’m on driver 566.36, and I’ve done clean installs, tried different settings profiles. DX12 theoretically should reduce CPU load, but in my experience, it’s made no difference, and sometimes it’s even worse.

As for VRAM, I’m lucky to have 24GB, so I’m not personally hitting that wall, but I do know someone running a 9800X3D with a 5080 (16GB VRAM), and they’re forced to turn things down to avoid memory crashes or stuttering.

Bottom line: I’m not saying MSFS 2024 is ā€œbrokenā€ I know it’s a complex sim. But something about how it utilizes hardware in SU2/SU3 still feels very off, especially in CPU vs GPU balance. I’m definitely open to suggestions and tweaking further, but I just wanted to clarify that I wasn’t blindly lowering settings expecting a magic FPS boost. I’ve been testing both ways, and the behaviour remains strange.

Happy to try any suggested config changes if you’ve got ideas. Thanks again for the insight.

We just followed your advice and reinstalled 566.34. We noted an overall improvement in performance and especially regarding colour rendition and detail.
Subtle details in shadowing and reflections are now evident again.
Installation of the Driver included deleting cache and also using DDU together with NV clean.
Kind Regards and thanks for the Tip.
ps. We use an FE3090 ti.

Hmm, with my 4070ti Super I didn’t revert to any older drivers, however I cannot complain about any CTD or stuffers outside of running out of VRAM.

From reading I’m doing one thing different than others - I enforce the use of the latest DLSS version and preset K using the Nvidia App.

Not entirely sure but maybe there is some sort of an issue by using the latest drivers using preset E (which is still the case on SU3 Beta) plus the DLSS 4 version currently used by MSFS 2024.

Others with the issue might test against this (if available on RTX30 cards).

Can’t confirm. My CPU (Ryzen 7900) is at around 20%, GPU (RTX 4080) is at 95 - 97% (without frame limiter) or at around 70% with Frame Limiter at 29 FPS, 2x DLSS FG, DLAA, 4k Resolution, A350 parking at EDDF or EDDM (handcrafted Airports) in 2024.

I can confirm that there is more or less no difference between 566.36 and 576.52. I did a clean install of 566.36, but its within 2-5% GPU, so within the measurement tolerance. Both drivers having no problem showing stable 29 (resp. 58) FPS in the mentioned configuration.

As I was following this topic, I felt the need to also test 566.36, as my performance with latest drivers was bad. Did all the ā€˜dance’ with DDU to downgrade to 566.36… unfortunately I’ve got a CTD with error ā€œGPU Device Removedā€. Any tips on fixing that?

specs:
ryzen 5600x (no pbo2)
rtx3070ti (no overclock)
32Gb ram (xmp - 3200hz)
PSU 650w
4k monitor

in game config:
4k native resolution
DLSS performance
fps limited at 30
FSR’s FG enabled
vsync enabled on NVCP
dynamic fps at 45
configs are mostly on medium due to outdated PC…

Remnants of the former driver can cause serious issues more than we think, at least based on my personal experience since the days of FS9.

If you are sure you did clean-install it, please take a look at this workaround (3rd post). You could always undo it easily: https://www.avsim.com/forums/topic/645158-dgi_error_device_hung/

Also, go to Nvidia App and disable automatic optimization for MSFS20/24

If you undevolted your GPU, set the voltage to default (assuming using MSI Aft). When default provides you stable sessions, gradually adjust. I am underclocking my GPU as well to give me lower temp and above all steady FPS

Since I reverted to 566.13, I am CTD free with the latest SU 3 Beta, and stutter free with MSFS 2020 SU 16 Beta (RTX 30 series here)

let us know.

DDU the drivers, get the newest ones, reinstall them without Nvidia-App, dont touch anything regarding ā€œoptimizationā€ (no stupid tools like dlss swapper, auto-lod, profile inspector), and dont use more than 2x frame generation. Thats the only way that MSFS2024 is running stable (5080 here).

What you are experiencing is definitely odd. Prior to upgrading to a 5090 recently, I was running a 3090 in my rig driving a 5120 x 1440p monitor at native resolution and 240 hz. No frame capping, no G-Sync, no V-Sync, just good old, unleashed performance. With all settings on Ultra, I was seeing around 45 FPS in MSFS 2024 with GPU usage pegged at 99% and CPU usage at around 20%. These numbers were with driver 566.36 only. With 572.xx and beyond, I was seeing CPU usage spike to over 80% at times and causing stutters.

My system specs then:
Z790 mobo
i9-14900K
64 gigs 7200 RAM
RTX 3090
Windows 11

By limiting your resolution to 1080p and limiting your frame rate to 60, you are definitely forcing your CPU to be the bottleneck. There’s a reason all online CPU reviewers run their CPU gaming performance comparisons at 1080p and not at more real-world gaming resolutions.

When either upgrading or downgrading GPU drivers I do NOT use DDU, but rather simply use the ā€œCustomā€ and ā€œCleanā€ install options within the nVidia driver installation package. DDU is a bulldozer rather than a scalpel and tends to scrub the OS too clean where it then lacks support for the monitors you are using.

I do NOT change any of the default settings in NCP or the nVidia App. I do NOT use any third-party apps to force settings or features not natively available in the in-game graphics settings. I do NOT use ANY of nVidia’s features, i.e. filters, DLSS, DSR, Smooth Motion, etc. I do NOT have any apps, browsers, chat sessions, screen overlays, etc. running in the background when I launch the sim.

Like you, I don’t really care about FPS as long as the sim runs smoothly. I care much more about getting every ounce of visual quality I can out of the sim, hence the reason I refuse to use DLSS or any other of nVidia’s FPS boosting cheats. In 30 years of using nVidia products (3Dfx originally) I’ve never seen a single ā€œfeatureā€ introduced that worked as advertised or didn’t cause more problems than it solved. In my opinion, it’s all a bunch of marketing hype and no substance.

So my formula? 1) Buy the best hardware you can afford; 2) run a slimmed down system by minimizing stuff running in the background; 3) use only the in-game settings to adjust visual quality and performance.

I’ve been tinkering with computers and software since the 1960s and what was true then is still true today–programmers can always write software that exceeds the capacity of the currently available hardware to run it. Nothing could be more true when it comes to MSFS 2020 and 2024. KISS and you’ll get the best performance your hardware is capable of. KISS principle - Wikipedia
