How do I set Visualize so that round surfaces don't facet?

Hi all

I try to render with Visualize, textures and shines suit me, but in terms of rounding, some are very sharp and smooth, others are hexagon-like, is there a parameter to manage this? Attached is an example, we can see that at the level of the axle and the big case the rendering is good, but that at the level of the black ring and the top of the green coating, it is facetizing.

Thank you for your answers
