开启NVIDIA控制面板,在3D设定的调整影像设定和预览,
　　选择使用我的偏好设定强调(M) ,
　　并把其调节为效能.

　　參考自BBCS的说明
　　If you have an Nvidia card and the game is running slow, open the control panel by right clicking
　　your desktop, go to adjust image with preview, click use my preference, and slide it all the way
　　to the left (performance).
