when being a game developer took pure genius and not just a few tutorials off the internet

I was hoping you'd mention this when I saw the title :) okay here's basically the run down from Wikipedia:

"Games use inverse square roots to compute angles of graphics programs must perform millions of these calculations every second to simulate lighting. When the code was developed in the early 1990s, most floating point processing power lagged the speed of integer processing.This was troublesome for 3D graphics programs before the advent of specialized hardware to handle transform and lighting. Computation of square roots usually depends upon many division operations, which for floating point numbers are computationally expensive. The fast inverse square generates a good approximation with only one division step."

you should provide what computional boost it was

Sure as hell original comments were improving computational speed
