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.
