solved Dcs Freezes randomly sometimes up to 25 seconds at a time.

I am trying to track down a really weird issue i have had with dcs in the last week or so. I am asking how I would inspect the logs/debug/where to look to find out how i can resolve this issue. Only happens in MP not sure if it happens in ST but happens in MT. Single player is fine nothing wrong. Is there a better networking debug i can see? I seem to have a 0.02% loss over the time I play. Happens with all A/C seems to be worse going from f-10 map back to cockpit but it is litterally random when it happens, altough last two times it happened after a missle was fired at me.

PC config:

mobo: Z790 tomohawk
cpu: 13700k (small undervolt to keep temps down 0.050mv)
RAM: 6000MT Corsair 32gb
NVME: 990 pro
GPU: 4080 TUF

Issue: Random pausing. Frame times randomly jump to 8-45 seconds. 

Breif: Had a gpu driver crash last week which cause kernal hangs. No crashes after fixing  but the DCS MT MP randomly had long frame times.

Installed: DCS OB latest with MT,
Scripts: dcs export script for my mfds, scratchpad plus, SRS
Mods: Just some Airframes requires for MP server.

Step taken to try to resolve:

1. DDU the drivers and clean install. This fixed the black screen crashing of games.
2. Updated Bios, Motherboard drivers, Drivers, windows 11.
3. Removed any scripts i wasn't running (like scratchpad etc) removed from the lua startups etc
4. DCS repair, clean. 
5. Removing fxo, metashaders 2
6. Replacing network cables.
7. Turning off SRS,VR in the settings. (i was seeing some 100's of messages from SRS in the log not sure it made a difference).

Anything else i can try or logs i can see what causes these pauses. People on the server say they don't experience it so i am thinking the mp server is OK.

Thanks!

Hi. This looks like some external program or script is messing with DCS. Try this:

1. In "Saved Games/DCS...", rename your "Scripts" folder to "Scripts_bak" (it will deactivate all of your external scripts).
2. In your antivirus software, add DCS main path (e.g. "C:/Program Files/Eagle Dynamics/DCS World/") as an exception.

One more thing: ensure your Windows pagefile is stored on your fastest drive (2.5" SSD or NVMe), and ensure this drive has enough free space (~50 GB).

Also, please attach your dcs.log (from "Saved Games/DCS.../Logs") directly after seeing the stutter.

Thank you I will try the suggested and report back. I removed all scripts except scratchpad plus and dcsexportscript but i'll try removing those and see.

Report: DCS is back to normal. But what happened is a mystery.

I did so much remediation i am not sure what caused it. But the final thing I did, was to disable vsync (i need it because only have 60hz tv). Play the game without vsync, the stutter went away. Put vsync back on and it's fine again. So not sure.

Your feedback is appreciated.

Checked your CPU temperature?

I have a pretty similiar problem right now, and I discovered my CPU just gets to hot.

Yes 63 deg top temp. Have 360rad and undervolted cpu. I think it was a vsync issue maybe.
