Different resolution in displacement

Despite settings which @StephenWoods shared with me I have difference in resolution, I have done everything what he did in his video tutorial but I don’t have that level of details.

His work is smooth.

My work is not smooth like his. I don’t know what I am doing wrong?

I think they look pretty similar, just the lighting maybe throwing it off a bit?

But your looks like clouds, and my looks like paper. Look this lines on my work, Are you thinkthe issue is light? What settings I have to change?

Check your subdiv modifier Odd not to see Cat-Clarke highlighted.
But you give no lecture time so it is hard to look up if Stephen did, plus you cut part of the screenshot off losing information to others.

In his example he is using Simple/Adaptive subdivision not catmull-clark.

Now you can see mz node settings

Tutorial setings for node and for modifier:

Just to confirm, you have the following settings:

  1. Cycles enabled, viewport setting to render preview
  2. Experimental Mode enabled in render settings.
  3. Adaptive subdivision ticked in the subdivision surface modifier, set to simple.
  4. Viewport Dicing set to 1 or 2 px in Render Properties panel>Subdivision ( 1px is higher quality but takes more memory/processing power), also the correct camera chosen in the dicing camera, and your are previewing the render through the camera.
  5. In the Material Properties panel you have either Displacement or Displacement and Bump enabled under Surface>Displacement.

Also sometimes when you make changes to the settings or the shader, the viewport will not automatically update the displacement, you can chagne to wireframe render mode and back to cycles and it will usually re-dice the mesh to show the new displacement.

Thats really all I can think of, but honestly, your viewport preview looks fine. It would be very hard to get the exact same result as me. Thers lots of randomness in procedural texturing, even using all the exact same settings, underlying changes inbetween different version of Blender can result in things not looking the same, even in the exact same file.
