Constant Stuttering on Multiplayer Servers

[Cyrics]

Hey,

Running a 9800X3D and a 5090 at max settings (FPS capped at 120).

Had also a i7-13700k before and no change.

This has been bugging me for a while now.

 

On most Multiplayer servers I get constant stutters like this:

(4YA server with lots of people):

(Random Empty MP Server):

 

Yet, on single player or some Multiplayer servers, its perfection.

(Single player:)

(Growling Sidewinder server with 20+ clients:)

(Empty Longshot server:)

 

What is triggering this stutters and how can I solve it?

From your log it's likely to be Tacview dumping a lot of data on busy servers with lots of air and ground activity. Try one of the previously stuttery servers with it disabled from your side.
You could check Saved Games\DCS\Scripts\Hooks\ and move/delete anything you don't need (I didn't see a reference to the OH-6 gunner script in the log - it's a known stutter cause in MP - but you did have a script error from vpcDuelSpawnGUI.lua)
Also you could open Saved Games\DCS\Scripts\Export.lua in a text editor and make sure that only expected items are in there.

Indeed disabling Tacview resolved all the stutters.

Scripts\Hooks\ only has SRS, Tacview and the vpcDuelSpawnGUI. I had stutters before addding that last one but will remove it again.

Had OH-6 before and removed it almost as fast since it was breaking any performance for me.

From my understanding of the Export.lua, everything is ok, but let me know... It's Winwing software, DCS-BIOS, Tacview and SRS.
 

local wwtlfs=require('lfs')
dofile(wwtlfs.writedir()..'Scripts/wwt/wwtExport.lua')
local wwtlfs=require('lfs')
dofile(lfs.writedir() .. [[Scripts\DCS-BIOS\BIOS.lua]])
pcall(function() local dcsSr=require('lfs');dofile(dcsSr.writedir()..[[Mods\Services\DCS-SRS\Scripts\DCS-SimpleRadioStandalone.lua]]); end,nil)
local Tacviewlfs=require('lfs');dofile(Tacviewlfs.writedir()..'Scripts/TacviewGameExport.lua')

If I run with Tacview saving local client only, everything works great again, but not having any other information from hostiles and etc, breaks the whole point of Tacview for me.

Your export.lua is busy but I've seen others running similar setups.
You could check if the MP servers you play on regularly have server-side tacviews. Some make them available for download.

Ok. After reinstalling Tacview AND DCS-BIOS everything is now stable and without stutters.

Thanks for pointing in the right direction @Moezilla
