Menu: Multi-player
Multi-player is an online activity where up to 10 racers from anywhere in the world can join in a session on a
particular track for a particular car class. You must be connected to the internet.
Session master
A multi-player session must be created by one member, he then becomes the session master and controls the
conditions for that session and may even restrict the drivers by requiring a password to join. He also controls
when to start a qualify run or race and when to close the session down.
Latency
All racers in a multiplayer session exchange packets of position, speed and collision information with the
session master. The session master computer puts distributes all this information to all the players in that
session. Sending these information packets costs time because it has to pass through many routers and
switches. The delay between sending and receiving a package is called latency. The time between sending a
package to the host computer and receiving a reply package back is called ping and is in milliseconds. A good
ping is under 100 milliseconds, a ping over 200 msec is considered poor.
It is therefore very important that the session master has a good to excellent internet connection (low ping)
and good upload bandwidth, and he should also have a powerful computer as that computer has to do a lot of
extra calculations during that session. If your internet connection is poor you should not try to create sessions
because the latency will be very high and this will affect the quality of the multiplayer session.
Special gaming modem/router
If you are serious about hosting VRC Pro multi-player sessions you may want to consider obtaining a special
gaming router or modem. Such modems give priority to multi-player packages, thus increasing the quality of
the session. Google ‘gaming router’ for more information.
Create session:
By clicking on Create session you create a multiplayer session for your current track and car class selection.
You can set the following parameters for your session:
Session Settings
Name
Create a name for your multiplayer session. You can overwrite the default session name with your own name.
Password
By adding a password to your session you restrict the session to only the members who you have sent the
password. A reason to have a password restricted can be to have a session with just your friends, or to
guarantee a certain racer level. You can send the password by e-mail, by internal message (mp) on the VRC
website, or by voice if you are using vocal communication, for instance through Team Speak . Communicating
this in the Multi Player meeting room is of course visible for all members present in the meeting room at that
moment.
You can hide the password while typing in case you don’t want anybody to see your password.
Allow client to start race
The session creator can decide to allow other players in the session to start a qualify or race session. This is
particularly interesting if you are planning a long session but are not always present .
