A Reddit user shares a full recipe for speeding up MOSS image generation on modest hardware (RTX 3060 12GB):
- Use the ComfyUI-Spectrum-MOSS node's Ultra fast setting (params like warmupsteps 4, tailactualsteps 2, windowsize 8.0).
- Pair it with the latest MOSS-Image-SFT-8-steps-dmd LoRA from Hugging Face at strength 0.2–0.4 to recover the skipped steps.
- Sampler settings: 50 steps, CFG 4, Resmultistep, Simple schedule, 2MP resolution.
- Verified to run smoothly on 12GB VRAM + 32GB RAM.
