Out of the box, holes will feature polygon like edges on any close view:
Facet scale is normally set to the part. This means, NX will generate display geometry tessellation (creation of triangles used by graphics cards to render solids, among other things) appropriate for the part model. Because the tolerance values are computed from the part bounding box, display precision gets cruder as the size of the model increases. You can select “view” to ask NX to compute the tessellation tolerances based on view scale as an alternative for larger scale models, or where you see frequent changes in scale.
