We recommend to make sure that the latency is small than 100 milliseconds if possible, even though the game is still playable with a higher latency. While you are playing after joining a game you can see the latency to the host in the upper left corner of the minimap, e.g. Also the network latency between the host and the client is as small as possible. Thus, you should make sure that the player with the fastest Internet connection creates the game. We recommend an Internet connection with an upload speed of at least 5 Mbit/s, while higher speed usually allow a smoother experience. The multiplayer experience is mainly defined by the upload speed of the Internet connection of the player that created the game.
