Hi,
I'm pretty new to Babylon.js, only started using it a few days ago, but really enjoy it, great work! 
I encountered some odd behavior with using deterministic lockstep on my setup, when running the example from the Animation page (https://www.babylonjs-playground.com/index.html#DU4FPJ#3) on my laptop's display (120Hz) the animation is twice as fast as on my connected monitor (60Hz) - tried with both Latest and Stable version, with both Cannon and Oimo plugins. My first guess would be that the algorithm is only prepared to handle low FPS, and does not take into account possible higher values. Also tried to dig in to the project on GitHub, but since I'm not that familiar with the structure, sadly I did not find the sources responsible for the behavior. Could some expert please verify my finding?
Thank you, keep up the good work, cheers!
