Ultra low FPS on MP servers

[pierre0000]

Hello everyone, 

I just upgraded my PC to a RTX 5080 and DCS runs smoothly around 200FPS on 4K except on MP servers where it is totally unplayable (32 FPS max no matter the graphical settings, with drops in the air around 5 FPS). 

The rest of my config : I9 10900K, RAM 64Gb, DCS is installed on an M2 SSD , win 11. 

What I don't understand is that both the GPU and the CPU runs only around 20% of their capabilities on MP servers, whereas in single player it goes normally to 80-100% for the GPU and 30-40% for the CPU. 

NB: 

- I uninstalled TACVIEW

- Disables GPU scheduling in windows

- Disabled game mode

- My drivers are up to date, the game as well

- NVIDIA Overlay is disabled

- I repaired the game, no error

- My paghe file is 65536mb

- I tried to rename the hook folder in scripts to hook.bak

- I uninstalled mods, just have current hill still installed but I do not see the link?

 

I attached my log. 

Thanks in advance for your help guys and have a great night/day

Cheers

Pierre

Update, it seems linked to the F4E ... On other planes, FPS range from 50 to 80 FPS, disappointing with my setup but playable

Sometimes, some MP servers run very slow especially lots of users, map, and low-level fly (airfields)....

Any chance tries a MP server with less users (says less 10) for the FPS test?

Thanks for your help! I tried , was definitely better, around 50-80 FPS , very unstable though. Whereas around 200 in SP .. 

As an example , on the contention server , I play with a friend he has a little better CPU but lesser GPU and he runs a lot better than me

Please review the following thread if it explains:

In general, we want the CPU bound in the most of time so that DCS can deliver the better play result, especially lots of AI objects (tree included)

Try setting your pagefile to auto. You have 64gb ram it is more than enough, and setting it to auto will be easier on your disk space. 

Multiplayer will always be more demanding on the machine, there is way more going on, and usually MP missions have 1000's of units.

Hello commander , thank you I already understood this subject but it got a bit clearer 

I will try to use the in-game performance monitor and see what happens 

What I don't understand is that neither the GPU nor the CPU go above 20-30% usage (according to the Nvidia monitor)

Shouldn't the CPU be around 90-100% if it was the bottleneck? 

And even if it is 4 years old , it is still a i9-10900K, it should give me more than 10-30 FPS right ?

Hello Big news , thanks for your help I will try that! 

I perfectly understand that the MP missions can be huge but I'm talking about 10 FPS , there must be some problem regarding CPU and GPU usage ?

Yeah 10fps with your system seems odd for sure, if you have a track replay that isnt to big, attach it so we can test it also. Just bear in mind some servers run many scripts and external databases which dont play well with track replays. 

thank you

Ok I'll get the track file and send it ! Thanks again
