Adobe Photoshop CS5 and Photoshop CS5 Extended White Paper
Normal—Is the default setting. It uses a large amount of GPU memory to support advanced OpenGL features
and should be selected if you regularly use the GPU-accelerated features in Photoshop.
Advanced—Uses the same amount of memory as the Normal mode, but enables more advanced features to
improve drawing performance. This setting is best when working in 3D or when working extensively with the
GPU-accelerated features in Photoshop CS5
Keep in mind that mode changes will only take effect after Photoshop is restarted.
The 3D section of the Performances dialog box contains a VRAM slider
similar to the memory control located in the Performance section. Use
the slider to determine the upper limit of VRAM available to the
Photoshop 3D engine. The total value is a percentage of the overall
VRAM available. A setting of 100% will still reserve a portion of the
overall VRAM for use with the operating system. Higher values will
help with overall 3D performance but may compete with other
GPU-enabled applications.
13. Choose the appropriate Photoshop file type
The file type you choose will determine both the functions and features that can be saved with the file as well
as the maximum size. PSD and PSB files maintain the most functionality but at the cost of file size, especially if
the Maximize PSD and PSB File Compatibility option is selected. The maximum image sizes possible in
standard Photoshop CS5 documents are as follows:
PSD (Photoshop)—2GB
PSB (Large Document Format)—4EB (Four exabytes
equals 4 million terabytes, which is orders of
magnitude larger than available hard-drive storage
space, but the format has been built to accommodate
future innovation.)
TIFF—4GB (Note that most other applications cannot
work with TIFF images larger than 2GB.)
Photoshop PDF—10GB (Individual pages are limited
to 200x200 inches.)
14. Set the Maximize File Compatibility option
Photoshop CS5 is the 12th version of the software and includes many changes, additions, and enhancements
since its initial release. In addition, today many other software applications are capable of opening Photoshop
PSD documents, such as Adobe After Effects® CS5 and Adobe Photoshop Lightroom® 3 software. To help ensure
that earlier versions of Photoshop or other applications such as Photoshop Lightroom can open your saved
files, Photoshop CS5 by default stores a flattened copy of the image within the PSD or PSB document when it is
saved. The advantage of this feature is backwards compatibility with Photoshop itself and better integration
with other applications, but the tradeoff is larger file sizes and slower opening and saving of documents. By
default, Photoshop CS5 will ask if you want to maintain compatibility whenever you save a PSD or PSB file, but
this behavior can be adjusted by choosing Photoshop/Edit > Preferences > File Handling. In the File
Compatibility section, you can use the menu labeled Maximize PSD and PSB File Compatibility to set
Photoshop to either always or never save this extra flattened image within the file.
15. Turn off thumbnail display
Some of the panels in Photoshop CS5 display preview thumbnails of
content, such as the Layers, Channels, and Paths panels. As you edit
an image, these thumbnails are dynamically updated to reflect the
new content. The more layers or paths in a document, the more
thumbnails need to be built, drawn, and updated, each requiring
system resources. To free up the resources allocated to this task, open
the panel menu and choose Panel Options and then select None to
turn off thumbnail display.
