baked normals appear flat shaded in 3D view

Hello,

although hi-res and low-res models are set to smooth shading
once applied , the normals texture(4096x4096) appear flat shaded (triangulated) in 3d view
I zoomed on the faces so they can be size-compared in both uv and 3d view


anything that I am missing ?

thanks

Please supple example blend file and normal map

I think I dont have enough details on my hi res mesh, but if I try to subdivide the mesh, blender crashes all the time
I’ll try with zbrush, it is more aimed/optimized for this kind of job

Zbrush more optimized?
Really?
Good luck.
Please supply example file, as Richard suggested.
