My test playground: Babylon.js Playground . You should add a model path when testing. Sorry I can’t share the models for some reasons, but I’ve tested many models on many PCs with chrome, firefox and edge, but they all have the same problem on 5.47.0. For the most typical situation, I use windows 1…

See my answers in this thread: [image] How to detect the completion of initialization Questions This PR will make sure that everything is ready before scene.isReady returns true, even when using the pre-pass renderer:

I don’t reproduce. I used this PG: https://playground.babylonjs.com/#G7B8J6#1 Can you test with WebGPU / Firefox (or another browser)? Maybe it’s a problem with your drivers(?)

Updated the PG just to print the elapsed time to load: Babylon.js Playground (babylonjs.com) , tested on Edge and FF and both were taking the same time. Are you sure you disabled the cache when you tested? Most of the time I saw was just regular download time.

Your playground works fine for me, I guess the model is too simple to reproduce the problem, so I updated the playground with the model from Loading time performance regression? . New playground: https://playground.babylonjs.com/#G7B8J6#5 .

Still the same thing for me between cascaded / non cascaded: first time I come to the page, it is 1.03 - 1.08s for both, then when I click on the “Play” button, the time is around 0.75 for both.

The elapsed time showed is similar with or without the cascaded, but the time from clicking the ‘Play’ button to the GUI shows is really different, around 5s with the cascaded and 1.5s without the cascaded. I’ve tested the playground over 5 computers and all the same problem, so I really don’t thin…

I can reproduce, I’m currently investigating the issue.
