Why is creo useless in wireframe mode when rotating the model or assembly.

Only when I turn off show silhouette edges so a little goes? Thanks

Because the graphics processor is much much faster at manipulating shaded triangles than it is at drawing lots of line segments. MUCH faster. See the lack of wire frame video games as a general reference.

It's even worse at hidden-line computations as these not only have a lot of edges, it has to constantly calculate the bits that are visible from those that aren't and given them a different appearance.

Catia was originally a wire-frame only modeler. No doubt they wrote a lot of software to handle wireframe or wrote software to maintain a capability the existing users were used to when they migrated to common hardware.
