How Sandbox Work To Increase FPS?

[Moriy]

Hi~
I have a model who can run 240+FPS in sandbox, but only 25+fps in my project. I remove most of code in my project, FPS only increase to 30+FPS. I use performance to analyse this question, I find the way sand box rendering scene is different from mine.
This is performance of sandbox:

This is performance of mine:

Why they are rendering in different ways.Thanks for any help

The sandbox does no magic to render so much faster. It is a single model viewer, so this will also influence rendering, especially if you are rendering an entire scene vs. a single model.

It would be great to see thee model that renders so fast on the sandbox but renders much slower in places like the playground. Would you be able to reproduce the behavior?

I check all my code, I find it is mistake that I put object contains engine into vue’s data, vue proxy all the things in engine. all calculates are slow.

Very low FPS with Vue

Hi guys! I was experiencing very low FPS (5-10) when using Vue instead of steady 60 FPS on the same scene using a plain HTML page. I was passing the engine object to the parent component to get the fps, that was the issue. The solution is not to Ref and/or emit the BabylonJS engine and/or scene object. (in other words, do not make them reactive) I didn’t dig deeper, but I think it causes multiple calls of the renderLoop or something similar. R. EDIT: repo demonstrating the issue: GitHub - R…
