Point of WireFrame and no Fog

I recently found a CF hack that works, Just wondering what the point of having the selection of Wireframe and fog is. Im failing to see what its actually spose to do to give you the upper hand.. Can anybody tell me what the purpose of these selections are?
chams and boxes are great.. but wireframe and fog im not seeing any benifits..???

Can you send me the link to the hack. Because i dont no really what you are talking about so i really couldnt tell you but if i see it i might be able to explane it for you.
Please reply =D

good its working !!!

fog is so you can see in maps with fog wireframe is mostly for show but you can see thru the map and know where the other people are but its hard to move with it
