DRAGP1 (System Variable)

When hardware acceleration is used, controls how many vectors the system draws when you drag objects within a 2D viewport before it checks for a new input sample from the mouse.

Type: Integer
Saved in: Registry
Initial value: 5000

A larger number results in more graphical vectors being displayed as objects are dragged. For best performance, it is recommended that you use hardware acceleration rather than software acceleration. DRAGP1 has no effect when dragging objects in a 3D viewport.
