This addon was intended to keep track of the player's latency and fps during raid. It currently works only when in a raid group and still is under development. Stay tuned.
Everybody in the raid needs to have the addon installed for it to deliver reliable data. When called (/rsys) a raid roster pops up and shows latency in ms and fps of every player in the raid, colored by latency.
This is my first wow-addon and my first LUA-project. :)
