When using this mode as to the standard it would be great if you could look at both processed images so I could compare. I believe you have had this option in past.
So far when trying out the V2 noise I am not sure there are improvements in the right area as at least the normal v2 does for sure remove more noise but it also removes a lot more detail too leaving a worse result than V1. Also most of the time I try the v2 options it crashes very soon after
