I have neither knowledge of net-related problems,
nor have I designed the net part of my game yet well enough,
bu I think that this is irrelevant !


The speed of the game played through the net does not depoend
on the size of the data transferred at each frame, but 
on the time the packet needs to go from joystick to client engine to 
client net,
there to the internet to some distant server (TIME! is lost), into the servers engine,
and then back to the clients.

if the delay time gets to great, game hangs or so
But you can't improve delay time

But I really have to admit that I dont
kniow what I'm talking about, cause I am a novice in Net stuff
as well as in 3D.
