periodic frame drop in multiplayer（3080 10700k 32g ram）

[shogun1546]

3080, 10700k, 32g memory, the memory usage is about 25g when playing. There is a frame dropping every ten seconds（I locked the maximum fps at 61）This situation only occurs on servers with more than 30 players（like EUR GS serve）Periodic freezes make the game completely unplayable，Does anyone know a solution?The game is installed in the ssd, full screen optimization has been disabled. I originally planned to buy f16, these stuttering completely ruined my gaming experience.I would be very grateful if anyone can give any suggestions

The frames is in the upper left corner of the video, you can easily find that every ten seconds there will be a frame drop

 

 

 

Interestingly, when the number of players is less than 40, the frequency of this problem will decrease a lot. I guess it is related to the CPU. Maybe I should wait for Vulkan API to improve this problem?

cpu usage is very unstable.

pic1 HT turn off 

pic2 HT turn on

 

I installed the game in samsung SSD, the reading speed is 3500mb/S

In your ht off image You seem to be utilising all the cpu cores … dcs doesn’t do that…  have you got HAGS enabled, what other apps have you got running in the background are you using dcs bios? Etc…

What is HAGS？

I dont run other software in the background (except trackir5, steam, msi afterburner)

Hags read how to turn it off here https://www.thenerdmag.com/how-to-turn-off-hardware-accelerated-gpu-scheduling-on-windows-10

Re other apps I’d be stunned if those were the only things that showed up in task manager…

Not every time the cpu usage is so high.In the video only one physical core has 70% usage, but there are still periodic frame drops.And I have already turned off the gpu scheduling

My 4-core CPU also runs at 90-100% utilization on all cores after I switched to W11. That's how I get 45 fps on GS server (no reprojection). All unneeded background processes killed and other PC optimizations done. I think W11 better distributes load among threads, or maybe DCS is not as single threaded as it used to be.

Hi！W11 means Windows 11？

Yes. Uff, I lost track, unfortunately, need to make a list one day, for future installs. Basically, clean up Windows from bloatware and spyware, turn off stuff that hurts DCS, overclock CPU and GPU, config NVidia and DCS for performance. The latest trick was to replace DCS folders with hardlinks.
