Wallhack trick

Hello,
i'm not good with typing english so ill try to explain,

I just have a GeForce4 MX4000 , then i downloaded GeForce controle penal and set the details to the lowest ( not 8bit color ) then i go on crossfire to test it , and it works great, but then i saw something strange , i saw someone hide behind a wall ( cuz of the low detail ) i only have this when i see someone from a very long distance [ Map black widow , at A side ]

[ Skip if u dont wanne read ]

U need a GeForce card
U need GeForce controle panel

Then go to t he penal and go to the 3D options and set it to the lowest detail

Then go on Crossfire and test it

lol

I try it with my ATI
