Lower the display quality of a layer to Draft. See Layer image quality and subpixel positioning. Select Draft 3D in the Timeline panel menu, which disables all lights and shadows that fall on 3D layers. It also disables the depth-of-field blur for a camera. In After Effects CS6, use fast draft mode while laying out and previewing a ray-traced 3D composition by selecting an option other than "Off" from the Fast Previews button. Deselect Live Update in the Timeline panel menu to prevent After Effects from updating compositions dynamically. See Preview modes and Fast Previews preferences. Display audio waveforms in the Timeline panel only when necessary. See Showing properties and groups in the Timeline panel (keyboard shortcuts). Disable pixel aspect ratio correction by clicking the Toggle Pixel Aspect Ratio Correction button at the bottom of a Composition, Layer, or Footage panel. The speed and quality of pixel aspect ratio correction and other scaling for previews are controlled by the Viewer Quality preferences. See Viewer Quality preferences. Deselect Mirror On Computer Monitor when previewing video on an external video monitor. See Preview on an external video monitor. Hide layer controls, such as masks, 3D reference axes, and layer handles. See Show or hide layer controls in the Composition panel. Lower the magnification for a composition. When After Effects displays the Composition, Layer, and Footage panels at magnifications greater than 100%, screen redraw speed decreases. (See Zoom an image for preview.) Set the Resolution/Down Sample Factor value of the composition to Auto in the Composition panel, which prevents the unnecessary rendering of rows or columns of pixels that aren't drawn to the screen at low zoom levels. See Resolution. Improve performance when using effects To the top Some effects, such as blurs and distortions, require large amounts of memory and processor resources. By being selective about when and how you apply these effects, you can greatly improve overall performance. Apply memory-intensive and processor-intensive effects later. Animate your layers and do other work that requires real-time previews before you apply memory-intensive or processor-intensive effects (such as glows and blurs), which may make previews slower than real time. Temporarily turn off effects to increase the speed of previews. See Delete or disable effects and animation presets. Limit the number of particles generated by particle effects. See Simulation effects. Rather than apply the same effect with the same settings to multiple layers, apply the effect to an adjustment layer. When an effect is applied to an adjustment layer, it is processed once, on the composite of all of the layers beneath it. See Create an adjustment layer.
