Save the Memory! Let your PS run as if

First open the Performance option, Location: "Edit"--> "preferences"--> "performance"

Memory usage

The appropriate increase in Photoshop memory usage can increase software efficiency, provided that the computer has enough memory capacity, the default 60-70% is actually sufficient. Of course, a lot of computer memory just just enough, processing photos will open the browser, chat tools, and so on, you should consider compressing the amount of Photoshop memory, to other software reservation space. In addition, if the normal use of Photoshop is not high, and just do some simple processing, you can also compress the amount of Photoshop memory.

History and caching

As the name suggests, "history" is the function of record processing steps in Photoshop, the maximum number of default logging steps is 50, if not used can be reduced to about 20. On the left side of the step record is the cache level and tile size, and the default value is 4. If you frequently work with files that are large (100MB level) and use a lot of layers, it is recommended that you choose a larger document, whereas a smaller document is selected. In general, the higher the cache level, the slower the file is opened, but the faster it will be processed when opened.

Graphics processor Settings

Here is to use the graphics allocation part of the display, Operation tasks, require users to have a separate video card, you can choose the "Use graphics processor acceleration operation" and "Use OpenCL" option. If the computer does not have a video card, it is recommended to remove all of the options, no longer consuming the core resources.

Scratch disk

When memory is exhausted, the hard drive will carry the rest of the work. The default scratch disk is the system tray, which adds to the already stretched partition capacity of the snow. It is recommended that the scratch disk and the system disk separate, but the system version may lead to performance degradation, so the best option for scratch is to select a solid-state drive.
