Was the MP code in 2.5.6 moved back a few versions?

I noticed that MP in 2.5.6 is really choppy. Suffering from a lot of lag and freezing whenever something happens anywhere on the map (e.g. someone joins the server = lag spike, someone blows up = lag spike etc.).

 

Now I know this is nothing new to DCS players, unfortunately, but a while ago, steps forward were made. I remember ED released a better net-code or something, it was tested first on WW2 server and then released I believe.

 

Now that I think about it, pre-2.5.6 the MP experience was a lot smoother, and I had almost forgotten how bad it used to be before the improvement.

Enter 2.5.6 now, where it feels like we have gone back to the stone age and it became almost unplayable as soon as more than 12 people are on a server.

 

FPS is also much worse in MP.

 

So I am wondering if something has been reverted to pre 2.5.5...
