having raytraced shadows already working it doesn’t seem likely that they would work on yet another dynamic + non-raytraced lighting solution that would have an impact on dynamic shadow filtering.
in short, I don’t see how any improvements to static lighting [which might or might not come from raytracing] or any improvements to runtime raytracing stuff will contribute to fixing the problem described on this thread (aside from the likely statement of “raytraced shadows are there, use them to avoid shadow filtering problems” that we all fear due to raytracing cost / adoption rate / etc reasons)
