最近被綠屏困擾，堡壘之夜一執行就綠屏，相當操蛋，搜了好幾天，試了好久，直到看到這帖子（http://tieba.baidu.com/p/5682594296）裡的回覆；趕緊關了Hyper-V，重啟試試，wonderful，完美！！

這是什麼道理呢？？（https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/about/）

Limitations

Programs that depend on specific hardware will not work well in a virtual machine. For example, games or applications that require processing with GPUs might not work well. Also, applications relying on sub-10ms timers such as live music mixing applications or high precision times could have issues running in a virtual machine.

In addition, if you have Hyper-V enabled, those latency-sensitive, high-precision applications may also have issues running in the host. This is because with virtualization enabled, the host OS also runs on top of the Hyper-V virtualization layer, just as guest operating systems do. However, unlike guests, the host OS is special in that it has direct access to all the hardware, which means that applications with special hardware requirements can still run without issues in the host OS.

主要是開啟Hyper-V以後，host主機（windows系統）也會執行在hyper-v虛擬層上，一些對時間或精度有要求的程式就會出現異常。
