Terrain texture in Unity is blurred.

Title says that all. This is what I have got: http://i.stack.imgur.com/KO6tQ.png

I'm using for now Unity 3.5.7, but the problem is in every version I use. Of course, I checked almost every answer. Nothing works. Or I missed something?

I'm using 3.5.7 because It suits me and my computer. Also, If it helps, the textures original value are 512x512 for grounds and 256x512 for mountains - I scaled them to 32x32 and 128x256.
