0 = off 1 = on

i want it off because when you are gpu bound it limits render ahead limit to 1 frame and sometimes you get a stutter when panning the camera or doing stuff and its annoying.  im used to having it set to default of 2 or sometimes 3 (forgot what the games default is triple buffering is 3) so i would guess its 2 either way ill take the slight hit on input lag to have have it at 2 than to have reflex on and having the stutter
