Maybe some average like RollingAverage is enough for you: > [@Decoupling Frame rate from movement speed issues](https://forum.babylonjs.com/t/decoupling-frame-rate-from-movement-speed-issues/9611): > > Hi, In order to ensure that players with a higher framerate don’t actually move faster I want to incorporate deltatime into my main game loop. However, several issues have arisen when trying to implement this in babylon.The following examples are based on the answers given in: fps-affects-game-speed-framerate-independence (on this forum). First, when I just update the position with engine.getDeltaTime() \* speed, there is a very noticeable jitter: [https://playground.babylonjs.com/#J6U7V4](https://playground.babylonjs.com/#J6U7V4) This… Also check out: > [@What's the difference between engine.getDeltaTime and scene.getAnimationRatio?](https://forum.babylonjs.com/t/whats-the-difference-between-engine-getdeltatime-and-scene-getanimationratio/61): > > Hi, I’m trying to understand the difference between engine.getDeltaTime and scene.getAnimationRatio. Can someone help me to understand it? Another thing that I noticed is: when using FollowCamera to follow an object that is moved using elapsedTime = engine.getDeltaTime, the camera goes tremulous. If I remove the elapsed time, the camera movement is smooth. Am I making something wrong? I’m using this code to move my object: let elapsedTime = (GAME.engine.getDeltaTime() / 1000), gravity =… > [@Which Best Method for Mesh Rendering (Updated Every Frame)](https://forum.babylonjs.com/t/which-best-method-for-mesh-rendering-updated-every-frame/2834): > > Hello guys , As i unity developer i just want to ask a quick question Which method in mesh class Match update function in unity … What it means i want each mesh to have it’s own update method rather use scene.registerBeforeRender() Which controls every update/render happens in the scene I’ve used those func’s mesh.onBeforeDrawObservable() mesh.onAfterRenderObservable() But Explicitly i don’t know if it’s best choice or not and i have little problem with it … cuz those methods can’t … > **[Controlling the render loop](https://www.html5gamedevs.com/topic/18215-controlling-the-render-loop/)** > > Hi, I'm writing an app that essentially only needs to render when the user does something. There are a few edge cases that cause one-time animations, all other stuff is a one time render situation. The main reason to avoid the render loop is that... Or reduce overall scaling (i.e. mesh sizes), so you can decrease your speed value. --- _[View the full topic](https://forum.babylonjs.com/t/mesh-intersection-is-not-trigger-when-one-mesh-is-too-fast/37801)._
