Use this tab to adjust the frame rate speed to reduce the amount of drop-out during navigation.
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.
