VIS is the process of splitting up the binary tree, it has nothing to do with lighting...
First do a FullVis on your map... then do a relight, the relight usually takes longer (If you only make a change to lighting, obviously just perform a relight). With quake 3 it shows you every step of the lighting, vis, and ai, i dont know why Raven decided to hide the steps from everyone...
