Wondering what the problem is

Basically, the attached file is a small simulator for a custom game engine i was working on. It was a movement system currently written in .GUI but i had scripted it to work for 2 players. Anyways, i tried playing it myself and everythign went smoothly. However, when i tried playing it online, everything seemed to be delayed quite a lot and it got worse. The game didn't slow down (there wasn't any lag) but all the commands were extremely delayed. I have no idea what would cause this and was wondering if someone could look at the map and give a possible suggestion.

Arrow key events always have a multiplayer delay.

what about that racing one, azeroth grand prix?

I mean that one is run on the left and right keys and it doesn't seem to be crapping out.

Then, perhaps you should look at the map to see if they do anything to handle the issue.

People have been reporting control issues with that map since its release

Adding onto Grand Prix, it lags hugly when the game is full, for all players.
I wouldent say theyre methods are great.

dang. i can't make the map work how i wanted it to then....darn.
