I’m having better results with this texture compared to most of mine. I’ll attach the file in case it helps. Similar to you I did a few different versions. Note that I’m using displacement and not “bump” in the physically-based texture settings.
We did a deep dive into this not too long ago and figured out a lot of stuff. It’s a little weird sometimes - Sometimes you have to increase quality, sometimes decrease. Pay special attention to the units and the scale of the object. If my object is really small I get a similar result to you.
With a little tweaking it’s a really really nice texture. The Ambient Occlusion helps it ‘pop’ and get the concaves to show up better. I’ve linked the texture to my normals but I’m not sure if that’s helping or not.
