Im experiencing some very high stutters during touchdown and I tried pretty much every fix suggested on the forums. When I land, GPU and CPU performance rapidly goes down and it stutters for around 1-5 secs. As both of them loose usage at the exact same time, I assume there has to be a problem with the data supply. The sim is located on an external SSD drive and it takes me around 3 mins to the main menu. In this case the only other bottleneck could be the network, right? If I do a speedtest I get a download of around 400mb/s and a upload of around 150, which is pretty good I guess. It’s also quite strange that these stutters only show up during landing and especially on the touchdown moment. My CPU is almost everytime on 100%, so it would be pretty logically that this is the bottleneck, but the load goes down half on the touchdown moment, so I dont think this is the big problem. My CPU is a i7-9700F and my GPU is a Nvidia RTX 2060 Super. I get around 30-35 fps normally, most of the settings are set to low. But thats quite OK I guess, because im using the Fenix 95% of the time. My GPU has a load of around 50-70%, depending on the phase of flight of course.
I would be really grateful for your help!
I started running into the same thing about a week ago. I’ve got an I9 9900K & 3080ti running my HP Reverb G2 VR. I’ll average 41 FPS through my entire flight from take-off until I land. As soon as my wheels hit the ground my FPS drops to 4 FPS and it’s almost impossible to exit the flight to get back to the main menu. Once I do, FPS jumps right back where it should be. It seemed to coincide with when I downgraded my Nvidia driver from 531.79 to 531.29 per Asobo’s suggestion. I just did a regular installation. After the issues I went back to 531.79 but this time I used DDUinstaller but it didn’t fix the landing stutters. I’m going to try using DDUinstaller again but going back to 531.29 in case there were some leftover files from the newer driver that were affecting it. I’m also on DX 11.
A couple of things: With such low gpu usage I assume you use 1080p in which case there’s no need for the low graphics settings as a 2060S should be comfortable with ultra. LODs (particulary terrain LOD) and traffic settings are the only things you need to keep low although clouds down to high might give a few more fps. The fenix is mainthread heavy so by reducing the imbalance between cpu and gpu performance can only improve.
As for the external drive, the first thing you should check is for firmware updates but also that a) it is not too full (15%-20% free space is ideal) and b) your usb connection (preferably either a blue or red port on your PC) is not allowed to sleep. I highly recommend disabling your packages drive’s virtual cache and increasing the one on your system drive to a (fixed) 15GB.
If your ram supports XMP make sure it is enabled and if it doesn’t then consider an upgrade.
Hello there,

I have a Samsung ultra wide screen, with a 5120x1440p resolution and a second screen, but its mostly unused. I also tried disconnecting the second screen, didnt help. So you dont think my network is a problem, especially regarding the fact that CPU and GPU usage goes down rapidly as the stutters occur, so mostly during the touchdown moment. I have an OMEN pc, so I cant acces the XMP settings in the BIOS. I already trief upgrading from 16gb to 32gb, but it ran at 2133Mhz and I wasnt able to increase it due to the fact that it is a OMEN pc.
Thanks very much for all the tips!
You have decent internet in theory, at least to your ISP’s relays but of course your location relative to the MSFS servers and whatever’s in between is the question. If it really is the problem you should be getting good performance at least some of the time.
But no I don’t think that’s it, gpu at 50%, cpu at 100% tells it’s own story not least that 30-35fps in the cruise leaves absolutely no headroom for heavy scenery, you really need to up that to 40 plus. Also search these boards for the shader cache fix which should help at touch down.
Also those Omens are so tightly packed that you possibly have heat issues and are being throttled under high load
So its possible that the GPU and CPU get too hot when loading heavy scenery, and this resulting in a loss of load, because it slows down to reduce heat. That would make a lot of sense. Im thinking about getting a new PC anyways, as the OMEN starts to get on my nerves and I want some better performance. But before this I want to make sure, that the problem wont occur on the new PC as well, would be a huge waste of money ofc. Im going to have an eye on the temperatures of the equipment on my next flight.
Thanks for your help!
You’re welcome - before you buy run the prospective new pc’s specs by on these forums and you will get plenty of good advice at whatever budget you have. Especially with the big birds CPU power is more important than gpu.
If you have your rolling cache turned on, try turning it off, it really isn’t needed with a fast / stable ISP connection and is known to cause this issue.
Im getting the same thing, good network, 3070ti, ryzen 5800x. I have tried putting the grpahics down to the lowest setting and the stuttering stays. I get throughout the whole flight. I have also deleted the rolling cache as well as turning it off and nothing works. I am currently flying the fenix A320 which I know brings down frames but the stuttering is consistent.
Your system is unbalanced and lowering graphics will only make things worse, raise them to ultra and lower LOD and/or traffic instead. With such a problem I’m assuming 1080p and I suggest you upgrade to 1440p or possibly 4k … If your monitor lets you you can create custom resolutions in NVCP to test how it will perform but ignore any blurryness as it won’t be apparent on a larger monitor should you decide to upgrade. Also research PBO undervolting for the 5800X, I have the same and mine now boosts to 5GHz without going above 76°C
Sounds like your GPU is struggling to handle particle effects, namely smoke on touchdown. Even if there is no visual cue, the script within the aircraft’s parameters is still calling for that routine hence the touchdown stutter. First I’d suggest finding a way to disable said aircraft effect if only to confirm the theory, and/or go into the Nvidia Control Panel tweak some settings there. Always make a note of your NCP settings before making changes so that you may revert back if required.
I have the same issue…Have a look and try the fixes on this post Freeze/Lags while touchdown - but fps around 50 while approaching - #80 by eduio13
, they worked for me … i still had the stutters when i re-named the FX files but what fixed it for me was renaming the Services.spb… but the down side is you wont see any service trucks etc ,now the landings are really smooth and the stutters are gone
