Showcase Images were created with Flux1.dev fp16 in PNG and include metadata & workflow
My tests are limited to ComfyUI / Steps 25 / cfg 3.5 with the Ksampler Essentials nodes.
Weighting 0.65 but you can test other setting between 0.2 and 1.0
I used the following sampler/scheduler combinations :
euler / simple, ddim / ddim_unform, lms / sgm_uniform, dpmpp_2m / sgm_uniform, heunpp2 / sgm_uniform, ipndm / linear_quadratique, uni_pc_bh2 / linear_quadratique
Some images have been slightly upscaled with an XL model (Pixel Alchemy) to reduce persistent noise on realistic renderings.
