About this version
R7j RC2 = Improved realism (lighting, colors, skin texture) and sharpness. Decreased chance of duplication at high resolution. For Single Pass Text-to-Image use DPM (better textures) or Euler A (smoother). Steps 8 gives smooth draft with simplified composition but more stable anatomy and env structures. Steps 40 w/ DPM gives good texture and mostly stable anatomy.
Rule for steps: 8 steps kinda works but gives smooth picture like LCM sampler but with any samplers; 16 steps starts to give details using contrast samplers like DPM++ 2S A; 25..30 steps sharp enough for single pass render, but small objects like eyes and fingers might be unstable; not yet tested on 40+ steps, but I don't expect significant quality improvement.
Euler A with CFG up to 6.0 and steps from 14 and greater works as LCM sampler for previous (DMD2 versions). Euler A gives low noise, very smooth pictures. Good for Text2Image with consequent HiRes fix using other samplers.
DPM++ 2S A + Karras with CFG near 2.5 and steps 20+ is good for realism and texture rendering/optimal to me as a Text-to-Image.
