Jagged edges when applying displacement map in Zbrush


My mesh, of which has 5 million+ polys at sub 5, is producing jagged edges whenever I am applying a displacement to it in ZBrush. My displacement map is imported directly from TextureXYZ downloads, so that isn’t the problem (RGB channels are not separated, though).

Before baking displacement, the displacement looks somewhat decent.

After baking displacement =

My meshs topology consists of squares.

What’s the typical workflow/proper way to apply a displacement map properly in ZBrush and why is my mesh producing such low-res/jagged displacements?
