2D 画布的图形渲染管道有多种实现方式。这些不同的实现方式具有不同的效果特征。启用此项后,2D 画布环境可根据画布的使用方式在这些实现方式之间快速切换,以便增强效果。例如,从使用 GPU 的实现方式切换为不使用 GPU 的实现方式。
There are multiple implementations of the graphics rendering pipeline for the 2D canvas. These different implementations have different performance characteristics. Turning on this flag allows canvas 2D contexts to switch between these implementations on the fly based on how the canvas is used in order to increase performance. For example, going from an implementation that uses the GPU to one that doesn't.
