Technical question to the programmer

[mrgenie]

How is CPU load done over the network while multiplayer?

-1) Fastest PC handles all the AI's?
-2) All PC's do the same work, i.e. if playing 10 players network, 10 computers are doing each single
calculation 10 times and then sync? (slowest PC is bottleneck)
-3) AI's are spread over the PC's like you'd do with multi-core CPU..

Why am I asking..
Would it make the game faster running a MP game and host on the fastest PC some tiny nation
which is irrelevant (Iceland, Saarland, whatever).. and then you play on some other computer(computers if MP) the actual nations you want to play with..
