Speed Tab
Use this tab to adjust the frame rate speed to reduce the amount of drop-out
during navigation.
TIP If this does not improve navigation, try switching off the Guarantee Frame
Rate option.
Frame Rate Specifies the number of frames per second (FPS) that are rendered
in the Scene View.
The default setting is 6. You can set the frame rate from 1 through 60 frames
per second. Reducing the value reduces drop-out, but can cause jerky
movement during navigation. Increasing the value ensures a smoother
navigation, but increases drop-out.
TIP If you want to restore the default values, click the Defaults button.
