A disabled hardware acceleration on your graphics card can cause AutoCAD cursor moving not smoothly (choppy, jerky, jumpy crosshairs) over your drawing. Hardware acceleration may be disabled as a result of using a non-certified graphics card.
Your cursor than acts like it slowly analyses snap points (even if osnap is disabled).
You can make your cursor faster and smooth by suppressing dynamic mode (DYNMODE=0 or F12), or by enabling hardware acceleration (preferred method). You can do so with the 3DCONFIG command, the "Manual tune" button, check the "Enable hardware acceleration" option.
Slow and jerky cursor movement can be caused also by running BitDefender virus scanner.
