Render differences for Smoothing OFF or Smoothing checked ON.

Rendered with Smoothing ON in tyhe render settings..

All other settings being the same in the General Preferences, and in the render settings.

The only difference between both balls is the "V" in the checkbox in the properties palette.

The left ball stays sharp edged, I removed the "V" there.

The right ball is Smoothed because its checkbox is ticked.
