Now everything is clear, thanks!
But, I think that if the renderer in the final turns all objects into polygons,
physics simulators also use some general scheme also bringing everything into
polygons(?) At what the Blender can not cope with very difficult geometry or
will consider very long. Time the insignificant used on converting of object in
mesh.
I doubt that you will be able visually to distinguish (different) the cloth
received on a mesh from the cloth received on own object
