V3 DESCRIPTION V2 was a nice improvement in many ways, it lacked NSFW aspects and had problems with male genitalia sometimes. Version 3.0 has a wider range of NSFW related aspects while maintaining/improving photorealism and quality.

SETTINGS:

DPM++3M SDE Exponential, CFG: 2-7, steps: 30-50 or DPM++3M SDE Karras, CFG: 2-7, steps: 30-50 or DPM++2M SDE Karras, CFG: 2-7, steps: 30-50

Seems like the sweet spot for photorealism in CFG is around 2-4.
