Hi simmer,
after long testing a lot of options to reduce the stutters, a friend of mine and me found a good solution, which reduces the stutters a lot:
First of all turn on Vsync 30 FPS !!! Most important because with locked 60 fps the sim is stuttering like hell. ignore the setting on the picture below.
Follwing all my settings with my rtx 3090, m2 ssd, ryzen 7 3800xt with asus rog strix 570-e.
Sorry, don’t know the language.
so what’s the solution?
I would actually Turn off VSync in the sim graphics setting. But set the VSync to FAST in the GeForce control panel.
I have 32GB memory and fs2020 load there is still plenty of room memory, about 30% free, but still have problem stuttering and FPS drop.
@MichaMMA is our expert. Listen to his knowledge.
I can only tell you a simple answer.
FS2020 will eat memory like crazy. Loves it.
Either increase it with Virtual Memory (Pagefile which is disk storage used like
real SDRAM (memory)) or add additional SDRAM.
I have 64 GB of SDRAM. @MichaMMA says I don’t even need a Pagefile.
But, I let Win 10 automatically manage it anyway.
Exactly, seems location specific. San Jose international in cal is one of them.
Especially if LOD is set at max. Flying for about two or three hours and Windows has committed over 50 GB of memory for MSFS on my 32 GB system. Upgrade time!
Need 64GB RAM? wow..
Nah, Chrome beats MSFS on memory usage any day. 
can you check in resourcemanager the commited memory for MSFS ?
( you see overall also in taskmanger )
But of course, I wrote “can stutter come from” .. there are million other reasons, e.g. we should not forget that this is a online-game. I own 64Gig RAM and it is also not ‘perfect’, but ‘ooookay’ for me.
no
System managed is allways good.. only in some cases this does’nt works fine.
full agree… exactly what I can see ( near 4k, mostly ultra ). But it is not at all such high usage, the common usage is about 20GiG working set / 30Gig commited. But I assume some mods needs additional memory.
yep… beside of the joke behind is this an important point. I seen many screenshot where users (with lower amount of RAM) play MSFS and have lots of applications open.
How users can clean-up here memory before start msfs, e.g. for testing, I described here.
sorry, it is german …
greets
I saw that. I will give it a dry. Right now, I am happy with the performance… I have got 32 GB of SDRAM …
greets
Can anyone replicate this one?
I flew to Vietnam,alongside the coastline and tried to make a low lever flight a little deeper in the forest.
I made 2 flights with the MB-339 and the F-15D
It was a complete S@@T SHOW ! I was getting like 15 fps or so.
Pushed Esc and clicked MAIN MENU return,only to come across another slideshow before returning to the main menu so i could exit to windows.
THIS IS GETTING OUT OF HAND !@!#@@
Specs
Ryzen 2700
GPU Radeon 6800xt Sapphire Nitro Plus Special Edition
32 Gigs of ddr4 RAM
1 Terabyte M2 Kingston
4K monitor 60hz
850 psu Corsair
EDIT I have all tooltips on the screen set to off and also windows game mode and xbox game bar OFF as well
EDIT 2 I turned off all mods(old usa bases) i had for Vietnam and went to fly again.No problems,well besides the minor stutter but nothing like before.
I closed the sim and went in again with all mods ON for Vietnam and all was well again.
So..completely random situation… WTH?
Hi guys. my advice running an RTX 3070 on an i7 9700k. latest Nvida driver, HAGS off and follow this dudes advice 5 Steps to Improve VR Performance | Microsoft Flight Simulator | Windows Mixed Reality - YouTube. I’m running a Rift S, so ignore the mixed reality stuff. I am running stutter free. Obvs. play about with your settings, I am mostly on medium, except for clouds on high. If you have a better 30 series you can obviously ramp them up. I am running stutter free. my best experience so far. we are getting there!!!
It’s not a setting or user-side issue that this thread refers to, the problem is the the CPU hangs for no reason on coherentGTDraw or Manipulators and drops the FPS from 60 to 10 randomly, something is clearly wrong, some people are affected, some are not, glad to hear you are having a good experience but a lot of user are not
I’m pretty sure this is not normal on High settings on a 3090 9700K @4.9Ghz
You are right LaKbessita, certainly a bigger issue in that case. Do you think dx12 will make any difference?
After a little bit of thinking, I’ve figured out why this is happening.
I have an RTX 3090 and an r9 3900x with 32GB of 3200Mhz RAM. The computing power of this PC is overwhelming. No game should run this poorly on my PC, in theory.
I tweaked my graphics settings to the absolute lowest they could go, and I was still running at 10 fps on approach into Chicago. So just to test it, I set them back to maximum, and then I changed my resolution to 4K even though I usually play at 1440p. My fps stayed the same. This tells me this is definitely not a graphics issue.
This started happening after the update where wind over coastal areas was added. Since I mainly fly over Chicago, that might explain why I was noticing a heavier load on my CPU. I think Asobo was just too ambitious in their asking of computational power. This sim is just demanding too much from normal CPUs and it’s not something multithreading can fix. If one core isn’t done, it’ll still hang the system regardless of whether the other cores are.
Another problem is CPU advancements are incremental, so the level of CPU performance Asobo is asking for is still maybe ten years away, or more. That’s the majority of the life for a sim.
The only solution is for Asobo to dial back the physics simulation. In a crosswind scenario, maybe just create 100 different scripted events that can happen on approach and playing a random one during approach, instead of simulating 100 different lines of wind hitting 100 different points on the wing.
The physics simulation is just too demanding. Asobo have got to realize this and scale it back. We have data on how flights ‘should’ look like and scripting flights based off real world data is realistic enough. Modern CPUs just can’t handle the level of physics simulation Asobo is trying to get out of them, and it’s making this once really fun game, extremely unplayable after each update.
Oh also that’s the reason why it gets worse after each update. The sim just adds more things to an already struggling CPU.
It’s a good theory but I don’t think that’s the case at all, the perf drop happens in the same areas it’s highly reproducible for the people that have it, and it happens in all areas not only costal and in all weather conditions, there is just something that happens in this areas that are hanging the CPU even tho it’s not on 100% on any cores, something that changed in SU3 (or potentially WU3 even tho I didn’t get it lots of people report they did)
I still think it’s gotta be the wind. Maybe there was a coding error. The sim is asking for something that the CPU just can’t deliver in time.
