While you can change tap register speed in accessibly options, I believe this is only for quicktime events (escape the grapple!) and it does not affect how fast you have to tap to sprint. I am not clear on why there is no option to change sprint to something other than mashing the run button, as this remains one of the most baffling decisions in the game. It does however allow you to “fast crouch walk” on a toggle as well, which I just realized.
