I'm talking about cross globe distances, where response times are somewhat longer due to physical limitations.
Can proper and good network coding negate that delay to a minimum where it feels so smooth that the player wouldn't even notice that he's actually connected to a server on the other side of the globe or will there always be falls that have to be taken with huge distances like that?
Say, a player from Europe connecting to a server on the west coast of the US.
Optimizing your network code is always going to be something you should do, but it can only do so much. The less information you have to send and receive the smoother everything will feel, but it won't shorten the distance that info will have to travel. Even AAA multiplayer games have to deal with this and have servers all over the world.
