Problem loading Scene Viewer

Jonas1

Hey everyone,

i am getting this Error messsage: "Problem loading Scene Viewer
Your browser isn't using hardware acceleration for rendering which is required for displaying interactive 3D scenes." trying to load a sceneView from esri portal in my virtual machine.

I was wondering how you implemented the check to see if hardware acceleration is supported since we need to implement the same check in our implementation to fall back to 2D if hardware acceleration is not supported. Thanks in advance 🙂

Hi Jonas

I think what you might want to do for a fallback is that you add failIfMajorPerformanceCaveat when you get the canvas:

let context = canvas.getContext("webgl2", { failIfMajorPerformanceCaveat: true });

// if this failed, it might be due to a major performance caveat
if (context == null) {

  // try again without the failIfMajorPerformanceCaveat constraint
  context = canvas.getContext("webgl2");

  // if it succeeded now the previous failure must have been due to that constraint
  if (context != null) {
    capabilities.majorPerformanceCaveat = true;
  }
}

Then show the message or fallback if

capabilities.majorPerformanceCaveat = true
