Is my understanding correct that the effectiveness of the Bevel Shader depends on the poly count of the normals for the object I'm applying it to? My buttons, top ridges of the console, and screws don't seem to bevel as aggressively to smooth the geometry as they do in the video, and I suspect it is due to me using lower edge-count when creating the circles for the buttons for example. I tried to edit the radius of the Bevel Shader to be either smaller (0.0001) or larger (0.1) but seem to be getting diminishing returns.
I'm not sure if the bevel in the shader depends too much on how many polygons the object has, but I tend not to use the bevel in the shader. I don't know why I think it is too taxing on the render calculations and I overall it's better to have bevel either in the modifier or in the actual geometry. Even if JL uses it on the tutorial, you can do it differently.

Right, I understand your point that it might not be the best way in future workflow. My question was to understand why the Bevel Shader didn't fully smooth out my buttons, and I was assuming that it was due to the lower edge/poly count of my button
The Input > Bevel fakes Geometry that isn't there:
Right, my issue was that it isn't smoothing out my buttons as it does in the tutorial. I did use a lower edge-count for my buttons when I created it's circles. If my edge-count is lower then the fake geometry that the Shader tries to create will not have much geometry to work with from the start.
Okay I think, yes, it was the polycount in the end that wasn't creating more curved surfaces with the Bevel Shader
I tried to create the buttons again and used the same material+shader on both
Oh right, I think I see what you mean now!
The amount of Vertices in the Circle, does make a difference; the Bevel Input, can't make a low-poly circle into a high-poly circle.
It has more to do with the angle between Faces, than with the amount of Geometry.
To be honest, this goes rather deep (especially for a beginner).
But as Omar already mentioned, the Input Bevel Node, is not used that much.
It's just good to know it's there, because in some special cases, it can be an absolute life-saver!
