    We´ve embedded a Verge3D-Modell into a Website. Everything is working fine, except in Firefox the site will heavily lag during loading.
    Chrome and Edge don´t have this issue.

    It looks like a general issue with Firefox. It happens with all the demos as well (tested on industrial robot, scooter and some others). Firefox freezes for a moment at ~60% and ~75% during loading.
    It´s not just the loading bar takes longer at this point, but Firefox will lag in general. For example try to resize the Firefox window.

    Is this a known issue? Anything we can do about it?
    It would be fine for us if the loading time would be longer, but we would like to reduce the lagging of the website.

    Thanks and br,


    As far as I know this is “normal behaviour”. The loading takes quite longer because Firefox doesnt support “Parallel Shader Compiling”. Depending on the scene this missing support can have quite a big impact on loading times.

    Besides that the raw performance seems also to be quite lower on Firefox than on Chromium based browsers. I dont really think that there is much what could be done on our/webGL/verge3d side, this would be the devs of firefox.


    Hey web,
    thanks for your reply and explanation.
