I have my settings so that my FPS at EGLL is above 48 but I have stutters while taxi around the airport. This happens in any airport. My TLOD is set to 50, OLOD is 100, other settings are mainly Medium. Ive tried so many changes in settings both in-sim and NVIDIA but can’t get rid of stutters.
Hi there,
A few months ago, we asked you not to use General Discussion for help. Please do not use General Discussion for help. I have moved your post to #gd-commsupport:tech-talk.
For future reference:
- Aircraft
is where you discuss current or future planes coming to MSFS as well as assistance with liveries. - World
is where you discuss scenery, airports, and weather. - Aviate, Navigate, Communicate
is where you ask for help with flying. - Tech Talk
is where you discuss installation, graphics, drivers, performance, CTDs, and hardware. - Menus & Activities
is where you discuss activities (landing challenges, bush trips, etc), plus anything accessed through the menus including the Marketplace, settings, logbook, cameras, etc.
Many things can cause stutters. However ive most commonly seen it on rigs where its loading from disk. Bring up task manager and leave ir running in the background and see if you get disk spikes at the time of stutter. A fast nvme drive really helps here.
I’ve got the same, even though the disks are not working hard (or at all). Like being on a runway for takeoff. Let say I go exterior, and start moving around the aircraft; Im on 60fps or more, and there is some sort of microstutter going on all the time in the “moving around the plane animation..or what to call it”. It’s not smooth. Same thing: Up in the air, Im tilting the wings fast from one side to another - and there is same sort of “stutter” in the horizon - its not smooth (stil high fps, but sometimes around 40 fps). I have tried all kinds of settings in the sim, in the NCP - and I dont feel any smarter. Not sure whats causing this.

Delete the rolling cache, then re-create it. Sometimes the data in the rolling cache isn’t “cleaned up” correctly, and as such it can become stuttery.
The cache will imrove things when its working normally, but sometimes (for lots of reasons) it can need refreshed.
While you are at it clear the Windows shader cache and restart your PC.

Hi
Thanks for your response. I don’t use rolling cache. I’ve also cleared the windows cache and NVIDIA caches too but with no luck.
Thanks anyways
Hi
Thanks for your response. I have MSFS installed on a nvme drive. I will try out your suggestion on monitoring hard drive spikes.
Thank you again
Sorry for the long answer.
Imagine Einstein is sitting on a train with his camera (viewport) pointing straight out the window. Up ahead there is a telegraph pole close to tracks and a windmill far away from the tracks. The train is moving at a constant rate. The telegraph pole enters the viewport and then whips past out of focus. However, the windmill moves steadily across the viewport in focus at all times. How can this be?
If you plot the change in angle between the telegraph pole and the center of the viewport as it goes by, it would look like a bell curve. As the pole gets closer to the center of the viewport, the angle gets greater and greater between frames. As the pole moves past the center of the viewport, the change in the angle starts to decrease.
The windmill appears to move steadily across the viewport in focus at all times because the change in angle between frames is small. If you were to plot the change in angle for the windmill, the bell curve would be much flatter.
If you look out of the cockpit at 90 degrees with your VR headset, or TrackIR control, (at a tree or runway marker) you get that weird double-vision or rubber banding affect. This is often referred to as stuttering. The graphics card sends one frame at a time to your viewport. Since the scene is moving across the viewport and there’s a small bit of latency before the next frame, you get the rubber banding.
This is why things coming at you from the front of the cockpit, or things far away from you when you look left or right out the windows, don’t exhibit this visual glitch.
Motion reprojection works by compensating for the movement of the viewport and for objects moving across the viewport. In 2D, there is no compensation. You might think what if I rotate the viewport at a rate that matches the telegraph pole? You’ve probably done this riding in a car. You move your head as the pole goes past, and it stays in focus. However, in the game you are not actually watching the tree or runway light move. You are watching a frame of the object after it moved. So, even if you move your viewport as the object goes past, you still get the double-vision affect.
Today, you either have to maintain very high FPS (not currently possible in MSFS), so the change in angle is so small you eyes don’t notice it (your brain does it’s own MR). Or, the MR algorithms have to get much better at generating frames that handle all the complexities of the scene.
Long story short, frames with objects that are close to the viewport and moving quickly across will be slightly out of sync in 2D. The trick is to look ahead at 90 degrees or left and right at no more than 45 degrees until everything is far enough away that this effect is unnoticeable.

i shutdown the pc unintentionally when i download msfs i shutdown when it is 64gb and i can’t resume the downloading how to resume
Thanks for your response. I will keep this in mind

@FijiPilot You don’t mention whether you are using VR or 2D mode, but I’m guessing 2D. If 2D, what is your monitor’s native refresh rate? Based on you mentioning 48 fps, is it a 144hz screen? Are you using vsync on?
I had exactly the same prob, especially over mountainous areas
And I realized that the problem is kinda related to win 11
i reverted back to win 10 and the prob went away .
Hi
Thanks for your response.
Yes, I am using 2D mode with a G-Sync monitor 1440p @ 155 Mhz. I don’t use v-sync On coz I noticed that it makes the view choppy when panning around the cockpit.
Thanks
Thanks. I will consider that.
@FijiPilot Ok, if you’re using gsync then your stutters probably aren’t caused by framerate/sync rate mismatches, unless you’re hitting the lower limit of your monitor’s refresh rate range.
To rule that out for sure though, you might try setting a fixed refresh rate on your monitor of 144hz and then locking your fps at 48 by enabling Vsync at 33% monitor refresh rate in the sim settings. If it still stutters after that, provided your fps never drops below 48, then it’s caused by something else.
this is happening to me as well. I have an RTX3090 rig playing on a 144hz ultrawide OLED monitor and getting a consistent 50-60fps. However when panning the camera both inside and outside of the plane the camera movement consistently stutters pretty bad. It’s very frustrating to watch and can give you a headache
Did anyone ever find a solution to this?
Any way to set the monitor to 60hz? I’m a 3080Ti, and I have texture resolution LOW with max framerate set to 45 in the NCP. HAGS ON. DX 11. DLSS Balanced.
It really varies from sim update to sim update. Had great performance in SU12, got a bit less in SU13 and now since SU14 it’s terrible. Really hope SU15 will make this workable again, because at this point it’s really unplayable for me.

i hope SU15 makes things playable again but I have a nagging feeling it’s only going to get worse as they add more and more spaghetti code

I still don’t get what’s affecting my stutters. One Day it’s perfectly smooth. The next day or the next time I play, there is stutters when I pan around the plane or in the cockpit. Sometimes I see stutters when looking outside from the cockpit, but that is not very common. I have tried to change servers but I can’t say I have seen any big difference. It’s a bit from time to time I would say. I have also change all the graphic settings even to the lowest and the stutters are still there.
2024 and we still don’t know what causing this! Omg..
I have also tried to turn on or off vsync in both game and Nvidia control panel. The weird part is when using vsync together with my g Sync screen I do get worse stutters. In the game settings that is. It is actually better when using v Sync in the control panel, NCP.
Yes my GPU seem to Run at about 100%. But once again it could be very smooth. It is like there is something with the plane or the Systems or the way the planes or Instruments are rendered or something like that. Also Clouds in layers Seems to be badly optimized.
