LAN game problem - client is laggy



Hi guys,

i have used this tutorial ( to make a easy game for two players over the LAN. When I test it on one PC (server and client) everything is OK. But when i try it on two PCs client is kind of laggy. Could it be because of many objects that are in the game so the server must send a lot of data and client must receive a lot of data? I am sending .exe file, so you can try it. (control the player with arrows and spacebar). Thank you for your advice!
