suggest you read that, than we continue talking about it
for our own culture and to know how to use it in DW

Figure 13 on that link is what's new in the patch. DW now traces that farthest-reaching ray that still penetrates the layer. Beyond that range, no detection. Up to that point, there's a slight range penalty for the curve of the ray, which usually results in a negligible signal loss. Note that those rays work in both directions- if you're hiding just above or below the layer, your cross-layer detections are going to be short.
