GPUParticles' Inherit Velocity property used to act strangely if the physics tick rate was lower than the rendered FPS, as velocity was tracked in the process and not in the physics process. This means that on certain rendered frames, the velocity was effectively 0 since there was no movement since the last rendered frame.
