Seeing vertices through my material

Hello, I downloaded jpg texture files to apply that on my object, but you can see the vertices through the texture. What causes that? I will attach a picture

Thank you for your help!

The strength of you normalmap seems to be a little high… and does the face normals have a nice orientation?? And it’s better to connect the vector input of the textures to a texture coordinate node so blender doesn’t have to guess (it may guess wrong).
