Stop using the balanced power plan for high DPC Latency problem: how to detect and how to solve

Well, this is a tiny but important knowledge and I just noticed it today.

First of all, you need to know one thing: if DPC Latency is higher than 1000 μs, it will cause some strange phenomena such as sound lagging, and the video games have low performance.

已确认新版Nvidia驱动在Win10双显卡下存在切换窗口卡顿问题（376.54驱动已解决）

重置了一次Win10，重装了一遍集显和独显驱动（在设备管理器内卸载并删除，然后重新安装Intel和Nvidia提供的最新官方驱动），发现出现了窗口切换卡顿的问题。具体表现为：

切换窗口会卡顿一秒钟，然后恢复正常。

关闭窗口时会卡顿一秒后才退出，尤其是任务管理器，百分之百复现。

点击窗口内按钮时会出现卡顿现象。

一开始觉得是显卡的问题，但是不想折腾硬件，于是先自行调整了系统特效选项，发现故障依旧。

Win10 Update just updated the Nvidia driver to 376.54 today and I have a method to install the old version which you want to restore

Win10’s update cannot be set to not update the driver and it always includes the driver that just released internal, not public. These versions’ drivers may cause some problems, especially compatibility problem.
