Massive stutters, especially in MP close to objects

[Ulukaii]

My DCS installation is suffering from massive stutters coming from CPU and I can't pinpoint the issue ... any recommendations appreciated!

 

Situation

• PC is an AMD Ryzen 7600 X3D with 96GB RAM and GeForce 5080
• PC is literally used only for DCS, ultra-fresh Win11 installation, DCS + plugins, few tools (Notepad++) nothing else
• My DCS setup is moderately complex with following plugins used:
  • SimAppPro and full Winwing MIP
  • DCS-BIOS for my simpit panels
  • TrackIR
  • In multiplayer, SRS

Problem Description

Many micro stutters and massive stutters in MP, especially when close to other objects (e.g. cold and dark on a carrier. ) Inbetween the stutters, if i do not limit FPS, theoretical FPS is 200+ . See Logfiles attached and video here: 

What I tried to solve the problem

Tried to solve the problem on multiple levels: BIOS, Windows, DCS. From the video above, it seems to be 'CPU-related so here is what I tried so far:

BIOS

• SMT off or on
• EXPO settings on, off etc

Windows

• Pagefile
• Process Lasso
• Unpark CPUs

DCS

• Followed https://www.youtube.com/watch?v=zKLp8QTwyDA
• Most graphics settings to low

 

Next steps

Pretty much exhausted, next step will be full win reinstallation unless someone can see the problem from the logs or video ... thanks!

Does this occur on Single Player as well, or only multiplayer?

Does this only occur when moving your mouse? In the case of the mouse drop the polling rate of your mouse to below 500.

You also have Winwing MFDs. Can you ensure that you aren't running DCS as administrator. You can confirm this by right-clicking on both your DCS shortcut, and your DCS.exe file, and after selecting Properties check under the Compatibility tab to ensure that "Run as administrator" is not ticked.

You're also running DCS from the bin-mt directory. Run it from bin instead. They're both multithreaded and bin-mt will be removed in the future.

You also appear to have kneeboard files with errors, mods? Remove / fix those as well.

Have you also additionally tried without all your other peripherals plugged in, i.e. just running vanilla without head-tracking, mfds, etc. to rule out any issues with those?
