VFX particles timestep - physics simulation

Hello,

I've issue with the current timestep management, my physics simulation behave differently depending of FPS.
I've read this was already discussed in the past, see :

Indeed, it would be nice to have a fps independent mode, when wanting accurate physics simulations.
