couldnt tell ya. In my mind the question is always "why handicap myself with something that could potentially cause added lag". Sure you might only be looking at a 1-10ms lag, one you probably would never notice. But as we all know it feels sometimes that things in BF happen on a sub 100 ms level. So even if that 1-10ms lag doesnt do much, to me why even chance it? If it causes me 1 death or gains me 1 kill over 6 months, then its better.
Also batteries.. Dont want to be changing them out during mid match.
P.S. If its just the thick usb cable you dont like, any usb cable will work. I switched that out right away with a smaller one for more movement.
