Particle Origin Shift at Lower FPS

Hi friends, I really am in need of some advice if there’s a way to fix the origin shift that occurs at lower tick rates in a particle system. I’d like to make the particles appear at their origin even at 30 fps, but because the initial velocity is from 550 to 600 in X, they always appear to begin much further away from their origin. I want the particles to fall with gravity, so I’m using a constant acceleration module applying negative acceleration in Z.

If I modify the initial velocity from 100 to 600 the particles will now appear at the origin but the slower ones will fall way too soon breaking the fluid spray effect. Any advice will greatly appreciated!

Thanks so much for your time.
