I have got into a better understanding of micropolygons and so far I think I have done everything well, I just don’t know if this is normal that it looks like voxels, there is a way to increase or reduce the amount to make it look more natural??
I think the problem lies with the way you sample the texture. Are there any interpolation options? It looks like the resolution of your mesh (with subdivision) is higher than that of your texture, such that the pixels become visible. Can you show your node / displacement setup?
So the interpolation settings seem to be right, but could it be that the textures you are using are high-resolution but pixelated themselves? As @Okidoki said, this could be a compression thing: if you upscale a low-resolution image, you may get such staircases.
