My movement in B&W2 is vastly different than B&W. B&W is smooth with no problems. In B&W2 the hand feels floaty/laggy (already done 125 polling rate, it fixed the initial mouse non-responsive issue). The zoom scrolling is also erratic, one small movement and it will zoom drastically. Is this how it just is in B&W2 or is there something I can do to fix this?
