When i am on addon airports i have the famous 2 second spikes ( tested payware LEBL and EHAM ) . Default airports no issue so at all
When i move the throttle an i am moving at 2 KNOTS … all is smoooooth an no issue at all
As soon as i stand still … every 1 or 2 seconds spiking again.
When i move terrain lod back from 200 to 100 i do not have the issue … BUT why no stutters at 2 knots then since LOD is the same and movement should cost more to recalculate in my opinion ???
First image with spikes STANDING STILL ( and stutters every spike )
Nope …. Why is it away once i go 2 knots ??
Completely smooth
When I stop … bingo stutter every 2 seconds ( not random but a clear 2 second pattern )
When i go 2 knots … same loaded … goner
When i am on runway stil and move 2 knots it does not make a difference in memory at all
You would expect the opposite
BOTH screenshots peak by the way … one is slightly
Lower because there is a fluctuation and the numbers move constantly ( picture taken at certain number )
Why does a mempeak sitting still cause stutters while a mempeak going 2 knots does not cause stutters. Same things are loaded
Reduce your settings, skip addons and show us a screenshot with at least 20% headroom in memory usage. If it shows the same stutters, you are right, if not, I am.
I can easily reproduce your problem by increasing my settings. And I can prevent it by choosing reduced settings. Therfore I know: peak memory usage over budget causes stutters.
Man …. you are not answering the real question.
Apperently uou can not read either …. i already posted in my first post with lod 100 its gone.
Also Check my screenshots BOTH are red over budget !!
BOTH
Standing still stutter ( over budget )
Moving 2 knots … no stutter ( OVER BUDGET )
I donot have to show you new screenshots with lower detail … because we all know the result !!! Lower detail is better performance . As i wrote earlier … i already tested.
As told before … the sim is butter smooth … nice and green and my system easily handles the sim.
Now id you know the answer on why only stutters standing still … please respond … otherwise please di not respond with open doors.
Yes. And this is your problem. It is YOUR problem. Reduce your settings and addons in a way, so memory usage is not red over budget, and we can discuss further.
Why do you think, the simulator shows this red error message? Since it looks nice? Be serious.
The question is not, why it works in a certain situation, the question is, why does it not work in all other situations.
Prove it. Show us the screenshot with stutters AND headroom in memory usage.
Yes, but also when standing still your memory usage peaked over budget.
If you are so convinced, you are right, why don’t you just show us a screenshot proving the stutters also occur with headroom in memory usage? Why? It is so easy.
And your memory usage did not peak over retail budget? Please show a screenshot.
Again, this is not the question. You are not searching a solution for the movig phase, but for the stand still. And the solution is: keep your memory usage within the budget. Believe me or not, it will not change the fact. There is no alternative.
I am not wanting a solution ( would be nice but its not more the annoying because ….. i runs smooth when needed … i do not stand still much in a simulator )
I want to know WHY .. thats all
What is the difference standing still and moving when BOTH ARE OVER BUDGET
Also .. i am asking the question in this thread … so you do not decide what my question should be. Simply answer my question … what is the difference
But that you clearly can not read either probably
Man in my fist post i told default airports do NOT have the issue and LOD 100 neither … and still you are whining on screenshots . You ask me to test while i tell i aleeady tested an nonissue … LEARN TO READ
Well not sure if my observations are exactly this- but it seems if I’m in constant motion looking up, down, left right etc or also moving around with an xbox controller things stay fluid. As soon as I pause- example would be programming MCDU then I look somewhere immediately get purple band. The rythmic stutter comes often when I download an update or reinstall and have to change all my frame caps, vsync etc. I’ve recently turned off gsync, capped frames to 60 (NVCP), 2x FG latest DLSS and F or M. This has given me the smoothest experience so far. Every day it’s a work in progress. I couldn’t cure stutters in latest beta so I reverted to stable build. 5090, 13900k, 64ram, fast internet. Max settings. I’ve tried going to rediculously low settings before and still there are issues. Maybe if I go to a vanilla airport in the middle of nowhere I could cure this issue- but what’s the point then? I fly airliners mostly in and out of large hubs. Many people who seem to be very happy with their experience are flying gen aviation in and out of small hubs. But I’m happy that Asobo seems to be trying to fix things. One day?
I have a dedicated flightsim system ( 4090 / 7800x3d / SSD / 32 gb ) … only windows and flightsim
Only addons with addon linker : dep / dest addon and ifly or pmdg airliner / batc with AI
Completely tweaked .. no virus scanner also.
Green bands all over.
Super smooth on heavy addon airports with AI aircraft when moving . 2 second rhythmic stutter when standing still
I also notice ( super weird to me ) that those stutters are very visible in cockpit when i look around with joystick ( headswitch ) or keyboard in cockpit.
But when i use mouse right button … SMOOTH ??
The Mouse free look moves faster and more erratic… but it removes the stutter ??
This is so weird its the opposite on what is logical
I expect stutters when i start moving the plane … or fast moving around views .. but then all is smooth for me
From the screenshot, it looks like you’re using an RTX 4090 at 4K.
Now for the uncomfortable truth: an RTX 4090 isn’t really powerful enough to deliver a consistently smooth experience at native 4K with max settings in demanding flight sims without using DLSS or Frame Generation. I know because I owned one.
It’s an outstanding GPU for 1440p, but after I upgraded from a 1440p monitor to 4K, I eventually bought an RTX 5090 specifically because the 4090 wasn’t enough for the level of performance I wanted at 4K Ultra. I’d rather be honest than just tell you everything should be fine.
I also noticed the “peaked over retail budget” information. That can have an impact on MSFS performance as well.
When you say “when I stop”… stop what exactly? Are you flying a UFO during the tests or an aircraft? Which aircraft is it, exactly? That’s a really important detail for figuring out what’s causing the issue.
Your post is missing some very important information needed to properly understand the issue:
Which aircraft are you testing with and what is the exact location/airport -RWY?
Please provide screenshots of your MSFS graphics settings and online settings.
What applications are running in the background? For example: FSUIPC, SPAD.neXt, FSLTL, or any other tools/add-ons.
Please provide your exact hardware configuration.
Could you please add this information? Without these details, it’s very difficult to determine what is actually causing the stutters.
I am sorry if i sound rude but please read the above
Again … stutters when still on runway ( demanding ones like eham or lebl fore example )
When i give power … and start moving at 2 knots …. NO stutters at the same rtx 4090 at 4k ( see TWO screenshots ). When i “stop” … stutter back
ALL ON SAME RUNWAY with same settings.
All bars green … no stutters flying at 4k … even moving a few knots
Ijust want to know why it stutters when its less demanding for my system …. STANDING STILL an not while i move
Why people keep telling my system is not good enough … DESPITE IT RUNS HOURS SMOOTLY … except standing still
Just for the record, and it’s not really a clue as to why this is happening for you (I have no idea!), but “standing still” is not really less demanding on the system. It’s still running draw and physics cycles the same as if you were rolling, flying, whatever. It’s still refreshing the frames and calculations at the same rate. The game engine doesn’t really “know” you are not moving in that sense.
You should answer the questions from @TenPatrol though as that might give some clues. Particularly if you have background apps / GSX or the like. GSX may be preparing something for ground services when you “stop” for example.
