How come this terrain looks really good in the rendered rhino viewport... but so bad in Vray? (pics)

So I have these maps and I am trying to make a texture from them. I applied the color.png one to diffuse and the normal.png one as a normal bitmap and when rendered in vray it still looks like trash. I also tried everything with displacement and my computer crashed a few times (gtx 1080 ti, i7 7700k should handle it).
