confirm this and did some testing

modded live-server (about 40 mods)average FPS no players:average FPS ~10 players:
latest update25k<1000
before update25k18-20k
vanilla server (no mods)average FPS no players:average FPS 1 player:
latest update4k3k
before update15k14k

Also confirm the same results, huge FPS drop on server after the latest 1.28.160402 update

Same for me, unfortunately. I've been noticing performance issues since the first 1.28 update, but since today's update it's gotten even worse — the server is now only running at 500–800 FPS.

confirming that the server FPS dropped by 30-40% after today's game update.

Can also confirm. seems to halve FPS per person connecting

Please fix it
It's impossible to play, everything lags

This is out of hand guys helis and boats were rough but cars and everything else was fine now it’s like D/C every 4 min

Server FPS dropped very much! Constant desynchronization of players and complaints! Return to how it was!!!

Hey guys, I was tinkering to fix this issue, I found that in dayz.gproj this line was added
"
PhysicsSettings PhysicsSettingsClass "{50C8B06FB4D5FA52}" {

 GridBP 0
}

"
I believe its linked with this thread as without this line server performance is much improved
Results, With PhysicsSettings without PhysicsSettings

fps       8000                          fps     27000

However, removing this line server side does not allow players to connect
Hope this helps

Meatman I think it’s this “ Changed: Temporarily increased the maximum size of 'ScriptInputUserData' to accommodate for Network IDs being larger” that messed it up for everyone on their patch notes

Hello there,
even after main DZ 1.28 update our server had good FPS:

  • empty 75-80k server FPS (Ryzen 9700x OC 6GHz)
  • with 60 players 12-15k FPS.

After todays update:

  • empty server has 35-40k FPS
  • with 60 players 900-1300 FPS

Im investing a lot of money into our community servers so im very glad we have great support from Bohemia and everytime i bought new hardware, you find a way how to degrade server performance. Just for info, we have 0 monetization, 0 donations, we do it for players, cause we like to do it.

Tbh i dont see a correlation between larger network ids and fps reductions, but i only came to share <3

I can also confirm that our server FPS has halved with today's update. I can also confirm that removing the PhysicsSettings PhysicsSettingsClass "{50C8B06FB4D5FA52}" { line from dayz.gproj returns FPS to normal, although it stops players from logging in. Hopefully, we get some support on this soon!

We have also lost around half of our performance since the update. This will make it impossible for us to run a full server.
