It is a weird one. That particular issue is generally specifically mouse related.
let’s look at the mouse input signal:
signal goes through usb to computer and is interpreted by the mouse driver (mouse driver issue?)
it goes from the mouse driver though windows to the game (windows settings issue?)
it goes to the game software that implements it. (Specific game issue?)
if it’s supposed to go through the driver directly to the game skipping windows and isn’t for some reason windows itself could be the delay (bios setting issue?)
