What is the tradeoff when lowering GPLs bandwidth?
Reducing the bandwidth can increase warping, and can also aggravate the strange things that can occur if you or the other players are running at less than 36 fps. Also, it is necessary that everyone be using bandwidth settings compatible with those being used by the host, or else they will not be able to connect to the host. In practice, the beta team has run many races with reduced bandwidth, and has found gameplay to be quite acceptable.
