Question about chams/wall hack

What is the difference between chams and wallhack, i know chams is like coloring the players a behind object color and a in the open color.

Also is it just me or is the new hack only show chams for people in like a 20 feet radius, not that its a bad thing but i usually die before they come up on my screen =\

Yeah, the chams aren't showing across the full map. =\

its helps anyway, prob in some time they r going to improve it, or make it vip :P


(sry for the english)

as my experience i turn full bright off and dont go to waverider it should show all field as it only shows like 20 yards if ur on waverider as thats alot of wall to go through thats my guess
