Qwen Image 2.1 on an RTX 3060: 45s per Image with Acceleration LoRA Recipe
Artefact_Design · reddit · 2026-09-26
A detailed Reddit writeup of Qwen Image 2.1 experimentation: after testing every published acceleration LoRA, the author settled on Pruna-Qwen-Image-2.1 with strength 2–2.5 (higher = sharper), a custom sigma-based sampler (implemented with Claude's help), and euler ancestral as the best sampler. The setup runs Spectrum Qwen at 8 steps, 45 seconds per 1024×1280 image on an RTX 3060. Character consistency is described as stunning, and the author rewrote the default prompt-enhancer instructions with Claude to improve reference-based generations.
