Weird Lines in the distance (texture and render)

As you can see in the picture above. There are some strange lines on the screen. When i come close to them they disappeare but you can see them from a distance.

I have imported this mesh with its texture from blender using .fbx. Because I exported it from blender i can just easily throw the texture on the mesh without using any script (Notice that this is ONE mesh) In blender i don't encounter those lines.

My question is now, What is making those lines? And how do i fix it. Is it a render problem? (Changing the Filter mode to Bilinear or Trilinear and changing the Aniso Level won't help. Bilinear and Trilinear will only make my texture to blur more)

Thx for your help.
