bad performance in multiplayer

[David198502]

i just recognized, that the game runs much smoother when i play singleplayer mode.now with the ubi logo deleted, i have only minor stutters and good fps.
but today i played on rebka1 server, and i experienced pretty bad stutters, mainly when engaging an enemy.its pretty annoying when you spot a spit dive on him and then have a two second freeze.i lost my oponent out of vision not only once today.

but i wonder why that is the case?
