Interesting observation. This is what was lurking in the back of my mind when I was playing Path of Exile. But I usually thought it would be very elegant to implement it in the form of Lisp macros that transform all the computations into fast code that would need to be executed every tick.

I also think something similar could be implemented for an in-game rig of animated characters. In order to cut off the computation of animations that don't affect the result in any way at an earlier stage — for example, when the character switches weapons. This could make animation code more CPU cache friendly as many conditions could be optimized out.
