This is an interesting question. Fps refers to the draw rate and how often the graphics processor can publish to the screen. The universe does have an update rate, the plank time constant, yet this would be more similar to the cpu clock which would be where upon everything changes data wise.
Given the theory that we are all in a superadvanced simulation, we still cannot know, for we are beings bound by this universe and we don't know how long it takes externally to process an update for our whole universe but we can determine that update takes effect in the plank time constant. Meanwhile as to whether the for can be determined, we are even further from determining that as we have no sense as to the viewing apparatus into our universe.
