Adobe Photoshop is a large, resource-poor app. Sometimes it can slow to creep or, worse, crash. If you're having trouble, there are some simple steps you can take to get it working again. Here's what you can do to fix Photoshop.
& # 39; Turn it off and then on & # 39; It's the most common tech support tip for a reason: it often works, and Photoshop is no exception. If you work with large files or photos, your computer needs to store a lot of data in RAM. This includes every file and its history, plus everything else Photoshop needs to keep everything running. All this can amount to quite a few megabytes.
If you've been open Photoshop for a while, it might catch up a bit. The simplest solution is to just close and reopen the app.
Restarting your computer can also work, especially if many other apps are running in the background or if you haven't restarted in a while. Photoshop performance is affected by what happens in the background. If another app or system utility has crashed, it may affect how Photoshop works, but restarting your computer will fix the problem.
Update Photoshop to the latest version
If Photoshop keeps slowing or crashing after you restart it, things get a little trickier. The first step to fixing recurring issues is to make sure you are using the latest version of Photoshop.
Open Photoshop and go to Help> Updates to open the Creative Cloud app. (If Photoshop doesn't open, you can also open the Creative Cloud app directly.) Click on & # 39; Updates & # 39; in the sidebar. Click the ellipsis in the top right corner, then select "Check for Updates."
If any of your apps need to be updated, they will be listed here with an "Update" button. You can update individual apps or "Update All" at the top right. ; click
Let the Creative Cloud go ahead and try Photoshop again Please note that the Creative Cloud updater does not automatically remove the old version from your system Every year the app changes (for example Photoshop CC 2019 has been replaced by Photoshop CC 2020), so make sure to open the latest version.
If you haven't done this in a while, you may also need to update your Windows PC or Mac. You can also consider the graphics driver & # 39 Update your GPU.
Reset Photoshop Preferences
If Photoshop does not behave as expected, it can be as simple as an incorrectly configured preference in an obscure dialog box instead of searching each setting and To test any tool, you can simply reset Photoshop to its default state.
To do this, open Photoshop and press Alt + Control + Shift on a Windows PC or Option + Command + Shift on a Mac. When asked if you want to "delete the Adobe Photoshop settings file," click "Yes."
When Photoshop opens, it's as good as new again
Disable third-party plugins
Third-party plugins are a common cause of crashes, especially if they are not updated to work with the latest version of Photoshop.
To check if any of these are causing your problems, open Photoshop and press Shift. When asked if you & # 39; load optional plugins and third party plugins & # 39; want to skip, click & # 39; Yes & # 39 ;.
Use Photoshop and see if the problem still occurs. If it doesn't then the problem was caused by one of the plugins you installed. Update them all to the latest version. If that doesn't work, uninstall the plugins one by one until the problem is resolved.
Customize Photoshop performance settings
To get the fastest performance of Photoshop, you can improve the performance by the amount of system resources it has access to. This won't fix crashes, but it can speed up the general work and some specific tools.
On a PC, go to Edit> Preferences> Performance. On a Mac, go to Photoshop> Preferences> Performance.
There are three sets of settings here:
- Memory Usage: Determine the maximum amount of RAM Photoshop can use. If you use a low-end machine, Photoshop will run faster if you increase it. However, this is at the expense of other apps you have opened.
- Graphics Processor Settings: Enable the "Use Graphics Processor" option to enable Photoshop to use it, as well as the CPU. Under Advanced Settings, you can select one of three levels – "Basic", "Normal" or "Advanced" – that increase the workload for the GPU. Start with & # 39; Advanced & # 39; and if you have any problems, call it back to & # 39; Normal & # 39; or & # 39; Basic & # 39 ;. Likewise, you can check the "Use OpenCL" option if your graphics card supports it, although this only speeds up some features, such as the Blur Gallery.
- History and cache: These determine how much information Photoshop stores in RAM. The three optimization buttons take into account your system configuration. Select the one that is most suitable for the type of work you do. You can also manually configure the "History State" (the number of "Undos" you get), "Cache Levels" and "Cache Tile Size". Increasing the "cache levels" and using smaller cache tiles will speed up moving and zooming in a document, but will take longer to open.
You must then restart Photoshop for your changes to take effect. 
Problems with External Monitors
It takes Photoshop a lot of math to display the edits you make in real time. This is doubly true if you are using a large external monitor with a low power computer.
If everything is left behind when connected to a large screen, unplug it and use your laptop screen instead. You can also adjust the resolution on the big screen to a level that your computer can handle.
Upgrade your computer
Photoshop is optimized to run on low-end machines, so the minimum system requirements are quite simple: a 2 GHz Intel or AMD processor and 2 GB RAM. As of 2020, the latest version will work perfectly on my MacBook Air from mid 2012.
A computer you use to view this site is unlikely to meet these requirements, but you should also have realistic performance expectations. For example, while my old MacBook Air can do and run most Photoshop operations, it doesn't do that quickly or without a lot of fan noise.
If Photoshop is constantly slowing down while creating 3D models or working with multiple large models, dSLR photos may hit the limits of what your machine can handle. Unfortunately, no amount of troubleshooting can fix this.
