The Dell BIOS is emulating the mouse driver as a PS/2 mouse. By design, the PS/2 mouse uses relative position for the mouse pointer, which causes the sync lag. DRAC 5 has a USB mouse driver, which allows absolute position and closer tracking of the mouse pointer. Even if DRAC 5 passes the USB absolute mouse position to the Dell BIOS, the BIOS emulation would convert it back to relative position and retain the behavior.
