After fiddling with settings for several days, I think I found something that works as well as Chroma is capable of without getting into the workflow black arts.

It's a slow workflow because Chroma is slow. However, it can give really good results.

Designed to work with 16GB of VRAM. May work with less.

Includes Ultimate SD Upscale and FaceDetailer with optional toggles to turn it on and off.

Suggested Settings for V2:
CFG: 1

Steps: 20

Sampler: DEIS_2M

Scheduler: Beta57
