Local Test of MiniMax H3: Flawless Cloth Physics and Temporal Consistency
papjak · reddit · 2026-08-06
A developer pushed MiniMax H3 to its limits with a complex physics test on an RTX 5090, yielding mind-blowing results.
The scenario involved a cat crawling under a heavy blanket and emerging. While older models typically melt or freeze during such collisions, MiniMax H3 flawlessly rendered cloth deformation and mattress indentation. Even more impressive, the cat maintained exact facial and fur consistency after being obscured for seconds.
Benchmark Stats:
- Hardware: RTX 5090 (24GB VRAM) + 64GB RAM
- Settings: 15s clip, 20 steps, 0.4 MP resolution
- Render Time: 320 seconds
- Memory Management: ComfyUI successfully offloaded the 32B Qwen3-VL text encoder to system RAM (peaking at 81%), keeping VRAM at 70% and avoiding OOM.
