lag

Hello, I made a multiplayer game (currently just 2 players)

Right now, the opposing players car, is kind of jerky and not smooth. Looks bad and other bugs arise because of this like during the collision detection.

I notice Snake is pretty smooth.

What are ways to reduce lag? I feel like I might be missing something fundamental in the way I'm sending and broadcasting. Currently my swf is set at 21 fps.

There is a good thread on this subject here: http://nonoba.com/developers/forum/multiplayerapi/what-method-do-you-use-to-sync-up-players

i dont get much lag i think its a great game

The game has come a long way since I first posted that message and the lag has become manageable. Thanks for your support.
