The physics' two water managers and the game's interactive floor simulation (the Deku Tree's ground webs) step their surfaces in fixed steps of 1/60 s, as many whole steps as the frame's time holds, and drop the fraction, so every frame shorter than 1/60 s ran none and the surfaces stood still above 60 fps. The new set owater (water_steps, on by default) calls the page between the division and the game's cut, which keeps the fraction per object; at 60 fps the count is the game's.
