Plz help.. thats keeping me from playing fs2004

ok so listen up... i have this problem with the terrain... i know its not a problem... its suppose to be like that but i want to deactivate it or something by anyway... the ground on 2004 has dots on it... something like u see in the pic.. on 2002 its not there... those dots are great for detailed ground in close view but when i see it from far i still see the dots and it makes the ground looks like a busy dots moving on it its hard to explain... hmm... like a white screen on TV (Snow screen) and its disturbing me... there is anyway to do it like in fs2002? as u can see... blured but smooth without dots! and mipmaping doesnt work its just like lowering the range i can see with details. plz help
