My game Stuttering every 20ish seconds, and when launching missiles and explodes, in 2.8 it never happened like this.   

I have i7-10700 ,32GB RAM,NVIDIA 3070 8GVRAM, game on SSD.   Loving DCS hope this can be heal soon.

Thank you and Hi Flappie, saw you been tracking some similar issues, hope this won't bother you.

Performance monitor like： Stuttering.pngScreenshot\log\track attached.

 

 

HEAVY STUTTER.trk dcs.log dcs_frame.log

The performance had a big issue at the end of the Trk. If the AI play their things correctly.  I got shot down by the end and all the explosions and cracking~ I can see dozens of peaks on the FPS monitor window, even when I'm Over G blacked out.

Hi. You have an awful lof of shader error messages in your log, 2 different episodes:

  • T+03'50" to 04'10"
  • T+05'35" to 05"45'

It looks like this:

I'm not sure what this is but maybe this caused the performance issue you experienced.

Yet, this is probably not the source of your issue since you say it happens every 20 second or so. I rather think you're affected by the core parking issue.

Just in case, you can try the temporary renaming of you "Saved Games/DCS.../Scripts/Export.lua" file if you have one. This way, DCS won't be able to call external scripts.

If it doesn't help, then you should check solutions for the core parking issue:

The Windows way

The CPU Unpark way:
