~~~~~~~~~~~
This can be used to turn Fract Delta on or off.
Fract Delta results in fractional delta calculation which has a smoother particles display effect.
The smoothness effect comes from more accuracy, especially in systems with high randomness or fast-moving particles.
It helps maintain the visual consistency of the particle system, making sure that each particle's motion aligns with its actual lifespan.
Without it, particles might appear to jump or move more than they should in a single frame if they are emitted at a point within the frame.
The greater accuracy has a performance tradeoff, especially in systems with an higher amount of particles.
