If you hunt for @Grabber523 in the search bar at the top of this forum, it will show loads of threads where he discusses the same issue. I’ve attached links to main points. Its up to you if you want a very long read in the threads.
Once all of your graphics settings are maxed out, increase render scaling until you are at or just under 32ms render latency for the GPU on the dev mode FPS monitor. If you follow the link I posted earlier, and read the thread, the entire procedure is laid out.
If you can’t get 32ms render latency for the GPU with the in-game settings (which equates to rendering in 8k, so I doubt you will have any headroom left), message me, and I’ll let you know the next steps to take.
Well, frankly, yeah. People with lower-end GPUs are already GPU-bound, so the CPU isn’t sh!tting itself trying to render frames to send to a GPU that is bored, waiting for something to do. Everyone with a 20 or 30 series Nvidia GPU, or a 60 series AMD is chasing their tails in circles messing with graphics settings (going lower and lower) or even worse, messing with .cfg settings and increasing LOD (which is LITERALLY THE OPPOSITE of what they need to be doing) trying to get rid of all those pes…
Ok, so your LOD is probably too high. You can use the fps dev tool to ensure your mainthread latency stays in the yellow.
For a reference, I have a 10700k @ 5.1 all-core, and 200 LOD is as high as that CPU can go before I get so mainthread limited that I get stutters.
Start with reducing your LOD, on the ground at the busiest airport you fly at, until the little yellow bar on your mainthread stays yellow. If you’re getting more than a tick of red every couple of seconds, your LOD is too high.
…
Ok cool, and just to clarify, make sure your photgrammetry is on, and all of your traffic settings are as high as you want them to be (mine are all maxed out), and all of your other GPU-bound settings (everything EXCEPT LOD) are set at max before you start tweaking your LOD and GPU settings, then go up or down from that as a baseline.
This sim can run on a potato if you know which settings do what. LOD and traffic affect CPU (“main thread”), and basically everything else, especially resolution …
150 LOD sounds about right for airliners on your CPU. Glad I could help, I’ve been telling people how to tune this sim for months, in various threads, and for the most part feel like I have gone unheard. Except for a few users, like yourself, who let me know my method works for them.
Sounds like you nailed your GPU load too. Enjoy your “new” sim experience!
And as a reminder to others looking for help: stop trying to tune using FPS or percent of load on your hardware. The only tuning metric …

Grabber523 I have a couple of questions please as I’d like to try your methods - when you are talking about the “yellow bar” in the Dev Mode FPS counter I’m assuming you mean green as mine shows either green or red? [/quote]
-If you re-read my previous posts carefully, I refer to the one labeled MAIN THREAD. All of the bars go from green to yellow to red based on how “slow” each measured metric is.
-All of those colored bars show render…
CPU headroom is important because the CPU being over loaded is the cause of the stutters. Even though the overall percent of usage is low, the threads can can only process so much information per cycle. Slowing down the FPS with the GPU load gives the CPU time to think between those cycles. That’s all there is to it.
Settings that increase FPS also increase stutters.
People who are trying to get the sim to run at max FPS in flight are also the ones experiencing the heaviest stuttering when t…
