A non-expert user on Reddit reported severe issues running the MiniMax H3 model via ComfyUI on an RTX 3060 (16GB VRAM). While generating a 5-second video at 0.3MP takes only 3 minutes, the output quality is extremely poor with artifacts, prompt adherence is very low, and Turbo LoRA along with certain attention optimization nodes have no effect.
