Deactivating these 2 options serves to increase the display speed in the editor by not updating the deformation when various changes are made. The options have no influence on the rendered result.

Camera Dependent

For camera-based mapping methods (e.g. Noise with Space: Camera), this option defines whether the deformation should be updated when the camera changes.

Backface Cull

If this option is activated, the sides of the object to be deformed facing away from the camera are not deformed, which also increases the display speed in the editor. Here too, this has no influence on the rendering result.
