GPU features added in Photoshop CS5

GPU features in Photoshop CS4 and CS5

  • Zoom enhancements. Smooth display at all zoom levels and temporary zoom. See Zoom in or out
  • Animated transitions for one-stop zoom. Press Ctrl+Plus Sign (Windows) or Command+Plus Sign (Mac OS) to zoom, and the image animates slightly between zoom levels. The zoom can be subtle.
  • Flick-panning. Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS). In the General panel, select Enable Flick Panning. Then, select the Hand tool and click-flick the image, like a flick gesture on an iPhone. The image glides smoothly to the new position. 
  • Rotate the canvas. See Use the Rotate View tool.
  • View nonsquare pixel images. See Adjust pixel aspect ratio.
  • Pixel grid. A pixel grid appears when zooming in more than 500% on an image. See Hide the pixel grid.
  • Adobe Color Engine (ACE). Color conversions are faster because the GPU handles the processing instead of the CPU.
  • Draw Brush tip cursors. Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS). In the Cursors panel, choose a Brush Preview color. Then, when you interactively adjust the size or hardness of the Brush tool, the preview color displays the change in real time.  See Resize or change hardness of cursors by dragging
  • 3D Axis. See 3D Axis (Photoshop Extended).
  • 3D Lights. See 3D Lights settings (Photoshop Extended).
  • 3D acceleration

Adobe Bridge CS4 and CS5 GPU features

  • Preview panel
  • Full-screen preview
  • Review mode

See Preview and compare images for information on these features.

GPU/OpenGL preferences in Photoshop CS5

  1. Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
  2. In the Performance panel, make sure Enable OpenGL Drawing is selected in GPU Settings.
  3. Click Advanced Settings and specify the following options:
    • Mode > Basic Uses the least amount of GPU memory and enables basic OpenGL features.
    • Mode > Normal Uses more GPU memory and enables GPU-based color matching, tone mapping, and checkerboard blending.
    • Mode > Advanced Provides the benefits of Normal mode as well as newer OpenGL advances that can result in improved performance.

      Note: On Mac OS, Advanced mode requires Mac OS 10.6.x. Advanced mode is not available in Mac OS X 10.5.x.
    • Vertical Sync Reduces tearing by syncing the frame rate to that of the display.
    • Anti-Alias Guides And Paths Allows the GPU hardware to smooth the edges of drawn guides and paths.
  4. In the 3D panel, specify Interactive Rendering options:
    • OpenGL Uses hardware acceleration when interacting with 3D objects.
    • Ray Tracer Offers slower performance but allows you to view shadows, reflections, and refractions when interacting with 3D objects.

GPU/OpenGL preferences in Photoshop CS4

  1. Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
  2. In the Performance panel, select Enable OpenGL Drawing in GPU Settings.
  3. Click Advanced Settings and specify the following General options:
    • Vertical Sync Reduces tearing by syncing the frame rate to that of the display.
    • 3D Interaction Acceleration Increases the clicking speed when working with 3D forms. If you experience drawing problems that correct themselves when you release the mouse button, turn off this option.
    • Force Bilinear Interpolation Tells the GPU to perform high-precision modeling and smoothing functions when you use a card that doesn't support those functions.
  4. Set the following Advanced Drawing and Debugging options:

    • Use For Image Display Doubles the video RAM used to display the main image when you use multiple images, large images, or large 3D models. Available only on display cards that have at least 512 MB of RAM.
    • Compositing > None Does not composite the image over the checkerboard (results in black over the translucent areas).
    • Compositing > Linear Uses a linear blending approach to apply the checkerboard compositing.
    • Compositing > Gamma Corrected Uses a perceptually correct approach to compositing the image over the checkerboard.
    • Color Matching Can be used to avoid the display of visual artifacts.
