Optimizing Objects Updated - AltspaceVR/AltspaceSDK GitHub Wiki
Objects Updated counts the number of objects that have been updated since the last frame. An update consists of a change to an object's transform or its material's color.
Note: The renderer flattens the scene hierarchy during a render call. This means that an update to a parent object's transform will cause updates to all of its descendant objects.
Animating the transform or color of an object.
Try to minimize the number of animated objects in your scene.
