I have a 4070ti.
I use Forge.
I proceed in two steps:

FIRST STEP (txt2img):

- DPM++ 3M SDE Karras
- Sampling steps: 60
- Approximately 1232 x 1700 CFG scale: approximately 3.3
- Adetailer: enabled with the “mediapipe_face_mesh” model + inpaint width and height at 1024 x 1024
- Perturbed Attention Guidance with scale at 1.5
- Kohya HRfix with block number at 5 and downscale factor at 1.235

SECOND STEP (img2img panel) :

I am performing an upscaling, so I am keeping the same seed and same CFG scale

- denoising strength at around 0.3
- tiling enabled
- Perturbed Attention Guidance with scale at 2.5

SD Upscale script enabled, with tile overlap at 200 and scale factor at 1.8
