Persistant Stutter

[Lord Farringdon 529]

Hi Guys,

 

I've looked through so many of the stutter threads here and on Flight Sim tech support till I'm blue in the face. but cant find any that specifically address or at any rate provide a solution for a persistant stutter, on average about once every three seconds or so while absolutely still on sparse ground in the middle of Australia. 

 

 

You can see the spike there and it drops the FPS down about 3 FPS every spike. 

 

I have deliberately curtailed as much as I can so that the CPU is hardly breathing and I am being limited by GPU but in the green. So I am on the ground at YMAG a very sparse,feild with the Cessna 152 a simple aircraft.

All AI                                     OFF

All Land and sea traffic        OFF

Wx                                        Clear Skies

Bing Maps                           ON    (have disconnected Internet and spikes still occurred)

PG                                       OFF

Live Wx                              OFF

Multiplayer                         OFF

Rolling Cache                   OFF

Developer Mode               ON 

Global Rendering             LOW End

Nvidea CP                       120FPS

Monitor                            4160 x 2160 (120Hz) 

DX11                               ON

TAA                                 ON

VSync                             50% refresh rate.

 

I have also tried DX12(beta) but nothing I do seems to change this. The fact that nothing seems to affect iit, reduce it or stop it, is as though it from outside the programme?

Any ideas?

Set vsync to 1/3 refresh rate and report back.

 Now 40FPS.  This obviously changed the CPU/GPU balance but the stutter spike is still there.  As before it loses about 3FPS when it spikes.

 

EDIT: My community folder is empty.

The first thing I would do is to open the Windows task manager (performance tab) to check if I can identify the cause which could be very well outside of the sim.

This is, of course, knowing that the Community folder is disabled and using a default aircraft.

What happens if you turn off online functionality?

Hi Dominique,

The Community folder is empty and it is a default aircraft. 

There are  only four apps in play: 

 

There are no other widows or background tasks that are doing anything of significance or in sequence with the spiking. 

 

Logical Processor 15 is doing all the heavy lifting (the main thread) with a couple of others helping while most of the others are loafing about or idle.

Again nothing in the way of spikes or jumps to indiocate something is happening in the CPU that might be affecting instructions to the GPU. But the output from the windows performance monitor seems to be at a very low sample rate so there could still be something hiding there I guess?

How about ditch Chrome while running MSFS. Don't know about Chrome, but Firefox can be hard on my system if running while I'm flying in MSFS.

Sorry, I did say I had turned off the internet before but I should have said on line functionality. But I have just tried that again, and no difference is seen.

I ended the Chrome task for about 10 minutes but again no change in the spiking. 

I have no problems with FPS and the normal stutters I get at heavy airports or with heavy AI activity are easily explained away as simply system bottlenecks assocaited with me using ultra everywhere!  

Anyway. It's late here in NZ and I need to get some slumber so thanks for your help guys. In the absence of anyone else experiencing this persistent spiking I assume it may be something to do with my rig, perhaps a discrete in the mobo or the graphics card on it's way out?  😬.

Might have to live with it until something incurable happens! 

 

Cheers

Having the same problem, but in my case the stutter only occurs if I am over a very busy airport or a TIN city.

Regular interval stutters? Anti-virus or windows defender. Exclude the MSFS folders (all of them, community older, offical folder, app data folder etc.) and see if it stops.

[Brocky120 65]

If you have Nvidia Reflex enabled in game, turn it off, also turn it off in NCP and see if that makes any difference, I noticed my mainthread times were a lot higher with it on (I get that its designed to be just in time but seems pointless from my experience)

What does LatencyMon say?

This is usually a result of something running in the background, typically a virus checker or anti malware application.

Have you excluded your flight simulator folder/drive from these?

You could just turn off any antivirus or anti malware programs you are using temporarily just to test.

Are you running the Steam version?  Another Steam user found that Steam would start a background program every second or so..
