PROPOBJLIMIT
Determines the maximum number of selected entities that can be tracked using the Properties and Quick Properties panes. If the number of selected entities exceeds the limit, the Properties and Quick Properties panes are disabled. When set to 0, the limit is turned off and selecting a large number of entities may be slower.
Reducing the limit of entities that can be selected and changed at one time can improve performance when selecting a large number of entities. However it can be helpful to increase the limit if you need to change a property on hundreds or thousands of entities.
