vsync

If you disable Vsync then your graphics card will continuously render without waiting for the last frame to be displayed in its entirety.

如果禁用垂直同步，那麽你的显卡将不断呈现，而无需等待最后一帧全部显示。

VSync, well, synchronizes things. It tells the GPU to wait for the screen to finish its line by line drawing before loading the next frame.

而垂直同步，顾名思义，就是用来同步的。它告知GPU在载入新帧之前，要等待屏幕绘制完成前一帧。

VSYNC? Vertical SYNChronization?

垂直同步？。

Due to this, you should generally leave Vsync enabled except when benchmarking.

由于这个原因，一般应离开垂直同步启用，除了当标杆。

Another possibility is that you have Vsync enabled.

另一种可能性是，你已启用垂直同步。
