Z-Image Turbo with ComfyUI
In my limited experience, eight steps using dpmpp sde with the beta scheduler produces very good results. 4K friendly resolutions like 1536x1536 or 2048x2048 are definitely worth the extra time.
It’s mind blowing how many combinations of settings can be tweaked without even getting into custom nodes. Resolution, diffusion model, sampler, scheduler, steps, denoise value, upscale, second Ksampler.
It’s really a deep rabbit hole. I feel like I’m always going to want a more powerful computer because there’s always going to be something new and exciting.
