The problem is that as you make the texels smaller, you make the entire map smaller
too - and the repitition of the map becomes more obvious. Your problem isn't
to do with filtering.

What you need to do is to build a much larger map. Don't just stretch the
existing map - that would make it go fuzzy (or blocky or something) again - and
don't just put (say) 16 copies of the existing map into the bigger one.

You need a map with more information in it.

As an alternative, you might want to consider going back to the original map
scale and adding detail texture (assuming you have a machine that can do
detail texture that is).
