ok, in that case, up the shader rate on the skin. like richardson said, hyperreal is an impressively large and detailed texture, along with the several other bits that goes along with it. increasing the shading rate basically decreases the number of sub-pixel calculations for materials and lighting per pixel. this is especially render-saving on scenes with very complex materials. because by going from a shader rate of .2 to a shader rate of .4 your effectively calculating 1/2 as much material as before (basically) defining the shader rate per object is very handy, as it gives you much more control over the details on the scene, rather than simply changing the minimum shading rate in the render window.
