Latency Lag bars

They display the amount of latency between you, other players and the server.

Technical: The blue and yellow bars represent the round trip ping from the server to the guest and back again, in the TCP game packet system. So, its the total of the time taken for a TCP packet from the host to be sent to the guest, and the reply to be sent back to the host. The yellow bar represents your own ping.

The green bar (which moves quickly) represents the number of "game packets" that have been already sent but have not been "used".

How to read the coloured bars:

1. all bars are barely visible / are very low, green bar is moving quickly - everything is OK
2. one blue bar is going up and changes its colour to red - a player is lagging
3. the yellow bar going up - you are lagging
4. extreme of (2) that player will time out.
5. extreme of (3) you will time out.
