No increase in a renders resolution through the renderer settings is going to produce a sharper image if the information in the texture directly on the object has had it's textures dummed down. You can't resolve data that isn't there. This is the key point. You can reduce the render shading rate to .001, but if texture filtering is left on default ‘Quality’ there will still be noticeable blur. Is a user advised to turn down the shading rate for each and every body part? There are generally less material zones than body parts and it's easier to just turn off texture filtering if you'd actually like to see your textures. The thing that gets to me is that e-frontier has set things up so that you must struggle against a myriad of poorly chosen default settings. I wonder about this.
