Running at hecking-fast framerates for faster simulation results

Hi! I have a simulation tool that’s running through a bunch of scenarios in headless mode, but I want to simulate it faster than realtime without just using time-dilation so that I can keep reasonable approximately fixed delta times. Ex: Running a 30fps sim at 300fps, but keeping the same delta time as 30fps so it resolves everything 10x faster.

Is there a reasonable way to do this? (suitable unreasonable ways will also be acceptable)
