you cannot use frame rate as a synchronization method. duke (when it was
able to do multiplay) is an example of this method. the slowest computer
ends up being the driver of the game, thus punishing players with higher-end
cards.. by using movement/sec, this isn't an issue. each player draws as
fast as possible, getting full use out of their card.
using frame-rate is also known as lock-step, and this is a proven disaster
in games that require positioning. Some games can get away with it
(starcraft, warcraft) because there are very few commands issued and the
graphics aren't that intensive.
you can check the newsgroups for duke and lockstep to get some history on
this method of networking.
