Your computer can use a lot of resources to display tooltips for each location of the cursor in the drawing window. If all tooltips are enabled, the cursor will display one or more surface names, elevations, and offset distances from multiple alignments. You can reduce the number of tooltips by changing the tooltip setting at the level of the drawing, the object type, or the specific object. For example, you can selectively show tooltips from some objects while suppressing them from others. For more information, see To Work With Object Tooltips.
