After you install the python script you can run the script and then >>>

Turn Texture Filtering OFF for the figure.

You could additional try setting the min shading rate to a lower value, by going into the render settings and clicking manual (aquire from auto), and then setting the min shading rate to a value closer to 0 (the default I believe is 1).

The script bsaically goes through all of the materials for the figure and turns off the texture filtering (the default I believe is Quality), and for hte DAZ figures (and texture maps) this causes those seems to appear.

Hope that helps explain it, or provides you with the necessary search terms.
