Adobe Photoshop CS5 and Photoshop CS5 Extended
White Paper
Recommendations
For best performance, pick a card from the Photoshop CS5 supported video card list (kb2.adobe.com/cps/831/
cpsid_83117.html) that has a fast processor and as much memory (VRAM) as you can afford. If you’re working with video
files and want to take advantage of GPU acceleration in Adobe Premiere® Pro CS5 software, you should also consult the
supported video card list (www.adobe.com/products/premiere/systemreqs) for that program to find an option that suits
both Photoshop CS5 and Adobe Premiere Pro CS5 environments.

Screen or monitor
The role the monitor plays as a preview mechanism cannot be understated. In addition to enabling a fully
color-managed Photoshop workflow from capture to output, the quality of your monitor and its regular
calibration are essential to ensure the accurate representation of your images on screen. Both Windows and
Mac systems ship with software-based display calibration utilities designed to neutralize color casts and
standardize contrast and brightness. For more accurate calibration, use a combined hardware and software
solution that measures the colors and tones on screen and then creates a custom profile for your monitor.

The minimum pixel dimensions for monitors is 1024x768 pixels, with
1280x800 pixels recommended. But displays with higher dimensions
will allow more efficient arrangement of the Photoshop application
framework (for example, panels, menu, and toolbar). You may also
benefit from spreading the Photoshop workspace over more than one
screen, which provides the option to work with images on one screen
and panels on another.

The range of tones and colors that can be displayed by your system is determined by the abilities of both the
video card and the monitor. The minimum specification for color depth is 16–bit color, but most video card and
monitor combinations exceed this recommendation by using a 24–bit color system. This equates to an 8–bits-
per-channel pathway for red, green, and blue channels from card to monitor, which is more than enough for
most users, as it is possible to display up to 16.7 million colors. But Photoshop is capable of working with
higher bit rates when supported by higher-bit-rate-capable cards and monitors. Employing a video card and
monitor combination capable of 10 bits per channel increases the display palette to a possible 1.07 billion
colors, making it suitable for color-conscious professional photographers who want to see smoother
gradations of tones and colors. More details about activating high-bit display mode, currently available only to
Windows 7 users, can be found in the “Key steps to optimize Photoshop CS5 performance” section.

Recommendations
Always employ a fully color managed and calibrated system. If you are working with high-resolution or complex images,
consider employing a multimonitor display system, but make sure that the video card you use is capable of supporting a
multimonitor setup. Windows users who want the ultimate in color and tonal rendition can opt for a card and monitor
setup that supports 10-bits-per-channel display. Look for display port connections when searching for cards and
monitors that support high-bit display.

Key steps to optimize Photoshop CS5 performance
Knowing which hardware works best for your work environment is just part of the performance story. To
ensure that your carefully selected hardware works to its full potential, optimize Photoshop and fine-tune your
operating system. And if you’re unable to change hardware, use the following guidelines to adjust Photoshop
and your operating system preferences to realize performance gains without added expense.

1. Allocate your scratch disk correctly
To set your scratch disk, choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences >
Performance (Mac). Then, in the Scratch Disk section of the panel, select the drive that has the most free
space—preferably not your system or startup drive. If you have other drives listed, you can also allocate these
as extra scratch drives. Photoshop will use the drive listed first until it is full and then move to the next drive if
even more memory is needed. You can change the order in which the drives will be used by selecting a drive
and then using the Up or Down Arrow keys to change its position in the list. Place your system or startup drive
in last position. The performance of systems whose Efficiency result (see boxout below for details) regularly
