I usually use Slic3r 1.3 but now I'm trying the new Prusa slicer 2.2 that offers new features.

I see that Prusa slicer creates a lot of support material when compared to Slic3r:

this involves two problems:

1. A lot of material is wasted
2. The structure is very difficult to separate from the model

This is my configuration panel in Prusa:

Is it a setting problem?
