I am not sure on the i13 Overhaul but I do have the perfect series which I use with V4WM.  I find it works very well and I also like the way you can control the degree to which the effect can be applied.  Most of the time it is automatic but with certain poses the ability to adjust the level of the effect is very welcome.

From what I could see of Overhaul it serves very much the same purpose but perhaps other users can advise.  In my case I was happy with what I had with the perfect series and therefore was not looking for another solution.  If I were, I would certainly try Overhaul as I have a number of products from the same vendor and have never been dissappointed

 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
