Rendering issue on iPhone

Hello guys, i am working on a racing game. and my problem is that my road texture gets blurred on iPhone. i have setup the Anisotropic texture to Forced on in Quality Settings and it made an it abit clear but still half of my road is blurred. by googling i got the Mip Mapping of textures but i think this is for basic version not for Pro. because in pro version i cannot see that option. is there anything else i am missing?

i,ll be really thankful if you give me any idea that where my problem persists.

Hey i have done that… for the new comers in unity. go to texture settings → Texture type “Advance” → disable the Generate Mip Maps.
