Broken: 2.80 Beta.

Short description of error
When adding the Subdivision Surface Modifier to an object, the option labelled "Optimal Display" does not work. Essential function to have when working with subdivision models.

Exact steps for others to reproduce the error
Add a cube, then add a Subdivision Surface Modifier to it, increase the subdivisions and turn on "Optimal Display".

For me this option is always on. Is that the bug, or are you seeing all wires somehow?

Maybe this comparison between 2.79 and 2.80 illustrates the issue (see attached image): To the left, with the "Optimal Display" turned on, we see lowpoly edges/geometry over the subdivided surface, whereas in 2.80 Beta there seems to be no difference between turning the setting on or off. The option as seen in the 2.79 example would be great to also have in 2.80.

Ok, in object mode with wireframe display mode or overlay, I was thinking about edit mode.

Ah, yes, it is looking fine in edit mode, but not in object mode unfortunately. Maybe this is by design, but I thought it was an excellent way to declutter heavy subdivided scenes and if possible to make it also work in object mode (since the checkbox is there but nothing changes visually), that would be very nice.

I've properly set ME_EDGERENDER flags now, but it is ignored in the draw manager. So guess rest goes to @fclem.
