Arma 3 Multiplayer very low fps

[MastaMedula]

I have a huge Problem with huge fps drop in multiplayer modes like wasteland atlis etc.
In singleplayermode, i have no problems, 40+ fps on very high.
If i play some Map in MultiplayerMode i get like 11-max 19 fps.
I tried all different Graphic Modes.
Spec:
Athlon Phenom II X4 945
Nvidia Geforce 570 @1280mb Palit
8 gb ram
840 EVO SSD
I tried like everything i found via google etc. (like CPU unparking, add -cpucount etc. @ properties...)
So any suggestions what i can try or some ideas would be nice.

Probanly a better cpu and/or gpu. I don't know the arma3 specs off Han it I know its a cpu demanding game

That´s the thing. Obviously i can run the game itself in sp with high to very high settings but in mp it drops heavily.

MP requies a lot more processing power, especially CPU wise. It has to track 32-64 players, their actions, attributes, etc, etc.
