RTX 4090显卡出图变慢是什么原因

请问下我用的RTX 4090显卡生成一个10秒的视频，花了一个多小时，比之前出图慢了很多，有时候cmd窗口看生成视频的进度卡住了，需要按下“enter”键才会继续生成视频，请问下是什么原因导致的？

The report mentions RTX 4090 video generation and a cmd window that can pause until Enter is pressed, but it names no repository file or test. Begin by reproducing the slowdown and the paused progress behavior, recording the generation settings and console output. Done would require identifying a reproducible cause and documenting a verified fix or workaround.
