Every user"s setup is unique & may require a different combination of techniques khổng lồ get the most efficient performance from Photosiêu thị. From the suggestions documented in this article, consider which ones khổng lồ implement within the context of your computer thiết lập, the types of files you use, và your particular workflow. There are four primary ways to affect performance in Photoshop:

The easiest way lớn improve sầu performance, without spending money, is to mix your Photosiêu thị preferences và fine-tune its features khổng lồ take advantage of the way you work và the type of files you typically work with.

The most dramatic way khổng lồ increase performance is by investing in faster & more powerful hardware. Your computer must meet certain minimum system requirements lớn run Photocửa hàng optimally. Running Photoshop on underpowered or unsupported hardware—for example, on a computer having an incompatible graphics processor (GPU), may result in performance issues. 

Set performance-related preferences

Watch this short Clip khổng lồ learn how to quickly optimize performance-related preferences in Photocửa hàng.

Photosiêu thị provides a phối of preferences (Preferences > Performance) to help you make optimum use of your computer"s resources, such as memory, cabít, graphics processor, displays, etc. Depending on your primary use case for using Photoshop và the types of documents you generally work with, different combinations of these settings may suit you.

Additional settings such as Scratch Disks, available on other tabs of the Preferences dialog, may also directly impact your computer"s running tốc độ và stability.

Performance preferences in Photocửa hàng

Adjust the memory allocated lớn Photoshop

You can improve sầu performance by increasing the amount of memory/RAM allocated to lớn Photoshop. The Memory Usage area of the Performance preferences dialog (Preferences > Performance) tells you how much RAM is available lớn Photosiêu thị. It also shows the ideal Photocửa hàng memory allocation range for your system.

By mặc định, Photocửa hàng uses 70% of available RAM.

Increase the RAM allocated to Photocửa hàng by changing the value in the Let Photoshop Use box. Alternatively, adjust the Memory Usage slider. Restart Photoshop to enable your changes.

To find the ideal RAM allocation for your system, change it in 5% increments & monitor performance in the Efficiency indicator. 

We don"t recommover allocating more than 85% of your computer"s memory to Photoshop. Doing so may affect performance by leaving no memory for other essential system applications.


If you experience out-of-RAM or out-of-memory errors in Photosiêu thị, try increasing the amount of RAM allocated to Photoshop. However, setting the RAM allocation for Photosiêu thị too high (>85%) could affect the performance of other running applications, making your system unstable. 

The best solution to this issue is lớn increase the amount of RAM to lớn your computer. Cheông chồng with your computer manufacturer for RAM specifications & compatibility.

Adjust cađậy levels

Cabít basics

Photosiêu thị uses image caching to lớn speed up the redrawing of high-resolution documents while you"re working on them. You can specify up lớn eight levels of cached image data and choose one of the four available cabít tile sizes.

Increasing cabịt levels improves Photoshop’s responsiveness while you work, although images may take longer to load. The cađậy tile kích cỡ determines the amount of data on which Photocửa hàng operates at a time. Bigger tile sizes speed up complex operations, such as sharpening filters. Smaller changes, such as brush strokes, are more responsive with smaller tile sizes.

Cabít presets

Three cabít presets are available in the Performance preferences. Choose the one that matches your primary use case/purpose of using Photoshop:

Web/UI Design: Choose this option if you use Photoshop primarily for website, ứng dụng, or screen thiết kế. This option is appropriate for documents having numerous layers of low-to-medium px dimension assets. Default/Photos: Choose this option if you use Photoshop primarily to lớn retouch or edit moderate-sized images. For example, use this option if you normally edit photos originating from your mobile or digital camera in Photoshop. Huge Pixel Dimensions: Choose this option if you work extensively with heavy documents in Photoshop; for example, panoramas, matte paintings, etc.

Cache levels

For finer control, specify cabịt levels manually; the mặc định value is 4.

If you use relatively small files—roughly 1 megapixel or 1280 by 1024 pixels—& many layers (50 or more), mix Cađậy Levels to lớn 1 or 2. Setting Cache Levels to 1 disables image caching; only the current screen image is cached. If you use files with larger px dimensions—say, 50 megapixels or larger—mix Cache Levels higher than 4. Higher cabịt levels speed up redrawing.

You may not get high-chất lượng results with some Photosiêu thị features if you set Cađậy Levels lớn 1.

Limit history states

You can save sầu scratch disk space & improve sầu performance by limiting or reducing the number of history states Photoshop saves in the History panel. 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 sầu operation, such as creating or modifying an adjustment layer, consumes little space. Applying a filter to an entire image, on the other hvà, consumes much more space.

Photosiêu thị can save sầu up to 1,000 history states; the mặc định number is 50.

To reduce that number, go lớn the Performance preference dialog. In the History & Cachesection, mix the the number of History States lớn a lower value.

Set graphics processor (GPU) settings

The best way khổng lồ optimize GPU acceleration, which speeds up screen redraws, is to keep your đoạn Clip adapter driver up to date. For instructions on updating đoạn Clip adapter drivers

See Update Graphics Driver.

GPU preferences

Photosiêu thị provides you with dedicated GPU settings in both the Performance and 3 chiều sections in the Preferences dialog.

Settings in the Preferences > Performance section

If a graphics thẻ is detected on your system, its name and Mã Sản Phẩm will appear under Detectected Graphics Processor in the Graphics Processor Settings area of the Performance section.

If your graphics card is supported, the "Use Graphics Processor" checkbox is enable & checked by mặc định. If your graphics card is not supported, the checkbox will be grayed out và not checked by default.

Advanced Graphics Processor Settings

To fine-tune the card’s performance, click the Advanced Settings button. 

Adjust Drawing Mode:

Basic: This mode uses the least amount of graphics processor memory to lớn run the most basic OpenGL features. Use this mode if the Normal and Advanced modes seem khổng lồ be less smooth in their performance. This can happen when you routinely run other programs that occupy graphics processor memory. Select this option if you notice bad screen redraws or slower performance when using GPU-accelerated features. Normal: This mode uses a large amount of graphics processor memory khổng lồ tư vấn advanced OpenGL features to lớn persize color matching, tone mapping và checkerboard blending. This frees the CPU lớn perform other tasks. Advanced: This mode uses the graphics processor most intensively. It uses the same amount of memory as the Normal mode while enabling more advanced techniques to lớn improve drawing performance. This setting is best when working in 3 chiều or when working extensively with the GPU-accelerated features. If this mode seems to perform less smoothly, try switching khổng lồ Normal or Basic mode.

Additional advanced settings:

Use Graphics Processor lớn Accelerate Computation: Enable to lớn improve the interactivity of warp and puppet warp pĐánh Giá. Use OpenCL: Turn this off if Blur Gallery, Smart Sharpen, Select Focus Area or Image Size with Preserve sầu Details vị not work as expected. Anti-Alias Guides & Paths: Disable if guides & paths are appearing too heavy or too wide 30 Bit Display: Enable to lớn increase the color fidelity on a monitor which supports 30 bit. Use native sầu operating system GPU acceleration: Enable to lớn allow use of macOS Metal and Windows DirectX 12 as appropriate.

Settings in the Preferences > 3 chiều section

The 3D section of the Performances dialog box contains a VRAM slider similar to lớn the memory control located in the Performance section. Use the slider khổng lồ determine the upper limit of the video clip RAM (VRAM) available to lớn the Photoshop 3 chiều engine. The total value is a percentage of the overall VRAM available. A setting of 100% will still reserve sầu a portion of the overall VRAM for use with the operating system. Higher values will help with overall 3 chiều performance but may compete with other GPU-enabled applications.
