1. Edit → Preferences → File Handling
Image Preview → Select Never Save.
Cancel background storage function. (If the background storage is cancelled and more files need to be saved manually to avoid software errors, it would be a tragedy. )
Stop the compression of PSD and PSB files (PSD is saved quickly after stopping, but the compression rate is low)
2. Edit → Preferences → Performance
Let PhotoShop use () memory: it depends, if your computer only runs? Photoshop CC 20 18 (do not reserve memory for other software), so that more memory can be allocated to? PhotoShop. This will greatly speed up the performance.
History and cache: There are three options: Web/ user interface design, default/photo and super pixel size, which will affect the speed of opening files. If you often open large files with few layers, then choose a super pixel size. If there are many PSD files, choose a web page/user interface design.
Historical status: it can be set to about 20, depending on personal situation, the default value of 50 is too much.
Cache level: corresponding to above? History and cache settings.
Cache collage size: For PSD files with more layers, select 128K, otherwise, just set it larger.
3. Edit → Preferences → Temporary Disk
If there are SSD users, set the temporary disk to? Not on the SSD? Users of SSDs can use VSuite Ramdisk. It should be noted that if the disk space is not used, multiple flash disks can be set here.
4. Edit → Preferences → Add-ins
Cancel starting the generator
Cancel the connection that allows expansion to the Internet.
If you don't use the extension panel, you can also unload the extension panel.
5. Edit → Preferences → Fonts
Check the font name displayed in English. If too many fonts are installed, the performance of using the font function will be greatly improved.
Through the above settings, although PS performance cannot be greatly improved, at least the operation process will not be so stuck. Want to optimize it? The startup speed of Photoshop can reduce the loading of plug-in filter materials.
