《教程》联想win10开机慢、黑屏时间长的解决方法

ULPS is a feature of AMD GPUs which are in a multi-GPU CrossFire configuration. You're correct in that it means Ultra Low Power State, and essentially, when enabled, it turns off the second GPU when it isn't in use. This feature sometimes causes problems with games and overclocking, and there are some cases when it does cause a slow boot.
这段话大概是说ULPS是AMD显卡的一个智能省点技术，但可能也会导致游戏问题和开机变慢。
