This can happen when you routinely run other programs that occupy graphics processor memory.

If Photoshop is running slower than expected on your computer, or if youre experiencing system freezes, lags, or delays while using Photoshop, try the tips and techniques outlined in this document.

Running Photoshop on underpowered or unsupported hardwarefor example, on a computer having an incompatible graphics processor (GPU)may result in performance issues.

From the suggestions documented in this article, consider which ones to implement within the context of your computer setup, the types of files you use, and your particular workflow.

Every users setup is unique and may require a different combination of techniques to get the most efficient performance from Photoshop.

Depending on your primary use case for using Photoshop and the types of documents you generally work with, different combinations of these settings may suit you.

The Memory Usage area of the Performance preferences dialog ( Preferences Performance ) tells you how much RAM is available to Photoshop.

Doing so may affect performance by leaving no memory for other essential system applications.

However, setting the RAM allocation for Photoshop too high (85) could affect the performance of other running applications, making your system unstable.

Check with your computer manufacturer for RAM specifications and compatibility.

You can specify up to eight levels of cached image data and choose one of the four available cache tile sizes.

Bigger tile sizes speed up complex operations, such as sharpening filters.

Smaller changes, such as brush strokes, are more responsive with smaller tile sizes.

Choose the one that matches your primary use casepurpose of using Photoshop.

This option is appropriate for documents having numerous layers of low-to-medium pixel dimension assets.

For example, use this option if you normally edit photos originating from your mobile or digital camera in Photoshop.

Setting Cache Levels to 1 disables image caching; only the current screen image is cached.

The amount of space you save varies depending on how many pixels an operation changes.

For example, a history state based on a small paint stroke or a non-destructive operation, such as creating or modifying an adjustment layer, consumes little space.

Applying a filter to an entire image, on the other hand, consumes much more space.

In the History Cache section, set the the number of History States to a lower value.

Use this mode if the Normal and Advanced modes seem to be less smooth in their performance.
