System Information
Operating system: Windows 10 Home
Graphics card: GTX 1060 6GB

Blender Version
Broken: 2.8 Beta
Worked: 2.79b and older

Short description of error
On 2.8 Beta when subsurfing an object If Optimal Display is checked nothing changes blender keeps drawing all edges.

Exact steps for others to reproduce the error
Just subsurf the default cube set the number of sub to 2 in the viewport and check Optimal Display then change to wireframe mode and u will see that nothing changes and Blender keeps drawing all the edges. Try the same with Blender 2.79b and u will see a diference between them.

Right now, after you turn on optimal display, you need to change the following setting to some lower value than 1 (try 0.86): Overlays -> Wireframe

Anything higher than .86 you will start to see the secondary edges that sub-d adds start to appear. Anything below 0.86 the wireframe of the primary edges starts to break up.

I personally don't like this design either, since it's not obvious these 2 options are tied together and most uses of optimal display don't require seeing the secondary edges.

@Sergey, should we just get rid of the Optimal Display setting? It does not feel like it belongs there anyway imo..

I think it's rather important and useful feature to have, otherwise viewport will become a mess real quick.

This is something for @fclem to look into. The overlay should respect edges which are set for display, and not force-display other edges.

Well, the intent was to have the possibility to partially draw the sub-D edges (with varying alpha). It only shown all sub-D edges with full intensity if wireframe value is 1.0. Anything lower is already lowering the sub-D edges alpha. Maybe we should just force the shaded sub-D edges at wireframe == 1.0?

Well, I would rather have it as it was on 2.79 and later cause this setting is important and useful not only improves performance as improves visibility in the viewport. The point is we should keep it simple and fast to use, I personally would rather have only one option instead of 2 options in different places.

This was fix some time ago.
