I highly recommend use one of the following samplers: DPM++ SDE Karras, DPM++ SDE, DPM++ 2S a Karras, DPM++ 2S a
3-7+ cfg, 7-12+ steps, Clip Skip 2, use a highresfix with 0.2- 0.5 denoise and use the foolhardy-Upscaler.
Don't use following samplers:
DPM++ 2M, LMS, Heun, DPM++ 2M SDE, DPM++ 2M SDE Heun, DPM fast
