Mesh/surface Display quality low - Rendered view

There are some strange things going on, mesh display settings are set to smooth.

Does anyone know how to set things up properly?

Thank you!

looks more like a problem with shadow settings.

otherwise blue image should also show the problem.

do you have other geometry far away? (can mess with shadow precision)

increase assigned GPU shadow ram in display mode settings and/or try to set a clipping sphere

for meshing issues:

use ShowRenderMesh
and tweak custom mesh settings for that object
use “detailed controls” the slider doesn’t cut it imho

check the detailed mesh settings in help

I did nothing, it’s gone for some strange reason. Just reopened Rhino.

Thanks for the in-depth explanation.
