SMOOTHLY LÀ GÌ

Setting the right performance preferences in Photoshop helps your computer run stably at the optimum speed without freezes, lags, or delays. Based on the resources available on your system, tweak these preferences to get the most out of your Photoshop experience.

Photosiêu thị provides a mix of preferences (Preferences > Performance) lớn help you make optimum use of your computer"s resources, such as memory, cađậy, graphics processor, displays, etc. Depending on your primary use case for using Photosiêu thị 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 speed and stability.

Performance preferences in Photosiêu thị
Adjust the memory allocated lớn Photocửa hàng

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

By mặc định, Photoshop 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 Photosiêu thị to enable your changes.

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

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

Note:

If you experience out-of-RAM or out-of-memory errors in Photosiêu thị, try increasing the amount of RAM allocated to lớn Photosiêu thị. However, setting the RAM allocation for Photoshop 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 lớn your computer. Cheông chồng with your computer manufacturer for RAM specifications and compatibility.

Adjust cabít levels

Cabịt basics

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

Increasing cađậy levels improves Photoshop’s responsiveness while you work, although images may take longer khổng lồ load. The cabít tile size 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 sầu with smaller tile sizes.

Cađậy 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, tiện ích, 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 khổng lồ retouch or edit moderate-sized images. For example, use this option if you normally edit photos originating from your thiết bị di động 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 cabít levels manually; the default value is 4.

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

You may not get high-unique results with some Photosiêu thị features if you phối Cabít Levels khổng lồ 1.

Limit history states

You can save sầu scratch disk space và improve sầu performance by limiting or reducing the number of history states Photoshop saves in the History panel. The amount of space you save sầu 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 khổng lồ an entire image, on the other h&, consumes much more space.

Photocửa hàng can save up to 1,000 history states; the mặc định number is 50.

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

Settings in the Preferences > Performance section

If a graphics card is detected on your system, its name & model will appear under Detectected Graphics Processor in the Graphics Processor Settings area of the Performance section.

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

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 run the most basic OpenGL features. Use this mode if the Normal & Advanced modes seem to lớn 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 to support advanced OpenGL features khổng lồ persize color matching, tone mapping và checkerboard blending. This frees the CPU to perkhung 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 khổng lồ 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 to lớn Normal or Basic mode.
