MiniMax H3 tested: Kitchen Attention gives a free 30% speedup, Turbo LoRA tanks quality

The author benchmarked two MiniMax H3 speedups with identical prompt, seed, and resolution:
- Turbo LoRA (fewer steps): quality tanks — soft and drifting at 8 steps, fully broken with heavy face artifacts at 4; audio holds up better than visuals at low steps.
- Kitchen Attention (faster per-step backend): keeps all 20 steps, cuts 30% off render time with zero quality loss; just update ComfyUI and set it in the attention backend node.
- Combining both confirmed the artifacts come from the LoRA, not the backend.
Verdict: skip Turbo LoRA for now; Kitchen Attention is basically a free 30% boost. Video review included.
