To use Freeze Layer Contents in the Composition panel

When OpenGL is enabled, layers that consist of moving images require significantly more memory on your OpenGL
card to preview than do still-image layers. Freeze Layer Contents speeds playback by showing only the first frame
encountered in a layer.
❖
Click the Fast Previews button in the Composition panel, and choose Freeze Layer Contents.

To enable or disable Live Update mode

When you disable Live Update mode, After Effects displays wireframe representations instead of the actual layer
while you move the layer in the Composition panel. The layer appears again after you stop moving it.
Do one of the following:
•
To enable or disable Live Update mode, click the Live Update button
•
To temporarily disable or enable Live Update mode, hold down Alt (Windows) or Option (Mac OS) as you move
a layer or as you drag the current-time indicator.

To enable or disable Draft 3D mode

Draft 3D mode disables all lights and shadows that fall on 3D layers. It also disables the camera's depth-of-field blur.
❖
Click the Draft 3D mode button
