ps will freeze after using it for a while, but it will be normal after reinstalling ps. Don't know why. The computer configuration is as follows?

1. Preferences—Performance Settings

1. The first memory usage

It represents the percentage of computer memory occupied by ps when it is running. Ratio, you can slide the slider to select the corresponding value, usually between 80% and 90%. Of course, you can also choose 100%. Without running other software, the selected percentage ratio is more The higher, the smoother your PS will run. Since I spend more time designing, and usually only open PS, other software is only used occasionally when there are special needs, so I chose 90%. For general photo retouching, you can choose about 80%. First, the photographic images are generally not very big, so 80% is enough. Second, when retouching, you may run LR or some other tools while running PS. For other photo management software, you always have to leave some percentage for other software.

2. Graphics Processor Settings

Check the box to use the graphics processor and click "Advanced Settings". The following panel will appear. There are three drawing modes: basic, normal and advanced. This It depends on the amount of computer memory occupied when you run PS. Normally, select Normal. This mode uses a large amount of graphics processing memory and advanced openGL functions to perform color matching, tone mapping, etc. It is more suitable for image editing, which can free up the CPU. Perform other tasks. Of course, when you choose, there will also be a prompt text below to tell you the different functions of each option. Check the last few boxes, as shown in the figure:

3. History and cache

Here I choose the third option, super large pixel size, which is suitable for Picture editing with large pixels and few layers is basically prepared for post-photography. After selecting Extra Large Pixel Size, the cache level and cache tile size on the right are automatically set. The history record is the number of times you can regret undoing while working. No matter which option you choose, it is 50 steps. The lower PS version may be 20 steps. Some people like to make repeated modifications on the picture. If there are too many modifications, they are in the history record. If you undo it and you can't go back, you can modify the number of historical steps here. The more steps there are, the slower the PS will run. If the computer configuration is average, we only need 20 steps.

4. Temporary disk

ps If the configuration is normal, check other hard disks. Multiple selections are also possible. Do not set it on the C drive. The C drive is the system disk and is run on the computer. When you are very busy, choosing a free disk with large space as a temporary disk will speed up the operation. As shown in the picture:

2. Set layer thumbnails

In the layer panel, there will be a thumbnail of the current layer in front of each layer, and a small preview in front of the layer Right-click on the picture to set the display state. We select small thumbnails and cut the thumbnails to the layer boundary. Thumbnails take up a lot of memory. By default, the previous thumbnails display the size of the entire canvas. , after setting, the boundary size of the layer content is displayed. If it can be reduced, do not enlarge it.

3. Quickly clean up PS memory

When you use PS for a long time, you will find that PS will be very slow. This is because the memory occupied by PS is not released in time while you are working. If It will be resolved if you close PS and reopen it. If you don’t want to restart the PS, you can quickly clean up the memory space occupied by the PS. Select the Edit menu - Clean - All.
