Supermodel Vicki (SMV) and Supermodel Morph Vicki (SMMV) aren't the same thing. I'm sure Jim will pop in and give you the in-depth details :) Because SMV and SMMV are basically Vicki, then I would assume the same amount of resources are used. I have 448Mb Ram + W98SE and have no problems using SMMV on a V2 base. For my tastes I prefer SMMV purely because I added all the morphs to V2 and can create any gorgeous face I want to go with SMV gorgeous body. The best part about SMV and SMMV are the clothes Jim keeps creating :) If you go to BBay and take a look at the clothing (if you're a closet Poser clothing junkie like me) designed for her, you'll see what I mean.
