Display mode of illustrator

illustrator has several display modes.

Preview on CPU

View> Preview on CPU

GPU mode

The GPU (Graphics Processing Unit) is a special processor that allows you to quickly execute commands for manipulating and displaying images. The GPU accelerates computations, accelerating the performance of a variety of design, animation, and video applications.
With GPU performance enhancements, you can accelerate Illustrator’s pan / zoom / scroll to 10x speed at 10x magnification (increased from 6,400% to 64,000%).

It seems that it can be displayed at high speed in GPU mode, but if there is a problem with drawing (such as when the preview is jagged), it may be better to try CPU mode.

You can read more about the differences between CPU and GPU in adobe’s article.

Overprint preview

You can display the printed state in which the colors of the upper figure and the lower figure overlap.

When “Overprint for fill” is set for the object, it seems that the upper object may become translucent and the lower color may be printed depending on the color, but in normal preview mode it is I don’t understand.
