Jul 5, 2018 · 1. Using subsurf will subdivide the existing geometry allowing you to create smother curved surfaces. If you are not dealing with curves (what you call "hard surfaces") subsurfing will only result in extra processing time and will increase memory usage.
The reason this happens is since you are using the subdivision surface modifier over a displace modifier (Actually the displacement on top in the modifier panel), then when you subdivide it, it also displaces more points which gives it a more jagged look and then its smoothed by the subdivision surface modifier.

Yeah, ngons aren't going to subdivide the way you want. Once upon a time, you couldn't have faces with more than 4 sides in blender. Then they added bmesh. And while ngons are extremely useful, subdivision surfaces will still turn them into triangles or quads.
For rendering stuff you probably just want to create a smooth model without any visible poly edges. But the lower your base geometry the easier it is to adjust, so you let the modifier do that mesh subdivding step for you non-destructivly. Still, the subdivide modifier needs some geometry or creased edges to hold the shape.
Subdivision is an easy way to add more geometry and details to your objects. This tool is widely used in 3D modeling of mane kinds. Especially you can find it useful when working with high-poly and even realistic scenes. Today we are looking at the SubSurf Modifier in Blender v2.92. It also should work with newer and older versions too.
3 days ago · Mode: Edit Mode. Menu: Edge ‣ Subdivide. Subdividing splits selected edges and faces by cutting them in half or more, adding new vertices, and subdividing accordingly the faces involved. It adds resolution to the mesh by divide faces or edges into smaller units. This process follows a few rules, depending on the settings:

Jun 22, 2020 · $\begingroup$ For the sake of the non-destructive workflow, at least consider saving a separate version of your file from before appying of the SubD modifier. As far as your issue goes, I find that in a similar project of my own, I get the same issue of the character's mesh taking on a different look after applying the modifier.
