The influence of frames per second option

In the Solidworks Motion, can you explain for me more about the influence of "frames per second" option?

In the SW Help, it is shown that the frames per second multiplied by the lenghth of the animationm specifies the total numner of frames that are caputed. Obviously, it makes the motion animation smoother. But when I make many motion analysis, it affects the generated result. As I know, SW use nuemerial integarion method tho solve the differential equations while satisfying the algebratic euqations at every time step. I wonder whether ''frames per second'' option is the element in numerical algorithm ?
