Question Is possibly +30fps in a Soft Body 3D simulation using Runge Kutta Integrator?

    I want to make a collision simulator between a car and a wall; I want to model the car as a soft body to give it a more realistic effect.

    I have been researching and I have found that one way to do it is to model the car as a mass-spring system, I have also seen that the realism effect varies depending on the integrator that is used, I am specially interested in the Runge Kutta Integrator as I have seen that it provides very good realism effects.

    I want this simulator to be able to run at an acceptable frame rate (24 or 30 fps at least), however I have never created anything like this (neither a soft body nor the Runge Kutta Integrator), so my question is, can even Unity be able to run a simulator with these characteristics with an acceptable frame rate assuming is well optimized? or am I being too ambitious?

    Any limitation is nothing to do with Unity at all and everything to do with your knowledge and skill and clearly nobody on a forum can tell you if you can personally do this or if you're being too ambitious.

    The Unity Physics (DOTS) system is written entirely in C# using the Job system for instance.

    So in short, yeah, go for it. :)
