Thanks for the detailed description! There are various things that can influence the performance of your animation in 3D. Without seeing the code, I'll list some of the general aspects to check: What mechanism do you use to trigger an update? Make sure to use the browser's built in requestAnimationFrame so you only perform updates when the browser is idle and has time to render it. This will also throttle the number of updates when e.g. panning. The size and complexity of your glb model (textures and triangles) will impact performance, but also make sure you create the PointSymbol3D and Object3DPointLayer instances at the beginning and reuse them in each update step. If you need to recreate them to change properties like the heading, use clone() instead of creating a new instance. This avoids having to reload the glb, even if it is cached. Related to the previous point, that is one of the advantage of using FeatureLayer.applyEdits() over GraphicsLayer. By updating the heading/roll/tilt through attributes and using a RotationVariable for each of the attributes in the renderer, you automatically reuse the symbol. With the latest version of the JavaScript SDK (4.26), instead of using a FeatureLayer, we recommend using a client side stream layer and push updates using StreamLayer.sendMessageToClient(). We've added this capability specifically for situations where you want to update your data very frequently (many times per second). The use case you describe sounds very interesting and we would like to hear more about it, technically but also on a use case level, I'll get in touch via DM.   ... View more

After creating and adding a slide (as shown in the sample you refer) to the web scene object, you need to persist the changes. You can use WebScene.save to overwrite an existing one, or WebScene.saveAs to create a new web scene. Note that the user needs to be authenticated to update or create a new web scene (portal item). If not already logged in, the API will automatically prompt for a ArcGIS Online username/password as part of invoking save / saveAs. Hope this helps, please let me know if anything is unclear! ...

Try this: https://codepen.io/arnofiva/pen/ExRONxX It's based on the online documentation, showing how to load and use fonts in label: https://developers.arcgis.com/javascript/latest/labeling/#fonts-for-sceneview CSS   @font-face { font-family: "FontAwesome"; font-style: normal; font-weight: 400; font-display: auto; src: url("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/fonts/fontawesome-webfont.ttf") format("truetype"); }   JavaScript   labelingInfo = [{ labelPlacement: "above-center", labelExpressionInfo: { expression: `"\uf024 " + $feature.NAME` }, symbol: { type: "label-3d", symbolLayers: [ { type: "text", material: { color: "black" }, font: { family: "FontAwesome, Avenir Next", weight: "bold" }, size: 10 } ]} }];   ...

Hi Victor, unfortunately we've been seeing the same issues with older MacBooks. It's not reliably reproducible, updating the OS or browser seems to have an effect. Also it's not just our API that's effected, other 3D applications relying on WebGL (e.g. Three.js samples) also show poor performance - usually depending on the complexity of the scene. One workaround for this specific line of hardware appears to be setting the WebGL version to 1, you can do this at the beginning of your application code through https://developers.arcgis.com/javascript/latest/api-reference/esri-views-3d-externalRenderers.html#forceWebGLContext Let me know if this helps. I'm a big fan of your paraglider app, would be nice to talk about it sometime!  ... View more
