So this number is obviously significant for anyone intending to get the best out of Quake, and to those who are trying to understand the engine.
But why is the hard FPS cap set at the seemingly arbitrary number of 72? 70 would have made sense, for that was the refresh rate of the common VGA low-res mode that served as an alternative to the conventional 60Hz 480p. The only meaningful property of 72 I can think of is that it's a multiple of the cinema-standard 24 FPS, but that seems like quite a stretch as a justification.
