Poor performance in Firefox + IE


Recommended Posts



I've setup a basic scene which consists of:

  • A plane (144 x 144) with a heightmap
  • A cylinder
  • A cube
  • Skybox

You can see an image in the attachments.


My issue is that the FPS drops from a stable 60 down to 20/30 when moving the cursor around.  Then even further when panning the camera.

This only occurs in Firefox 42 and IE 11, Chrome is perfectly fine - no FPS drop at all.


As this scene is minimal, I was wondering if it's only a bug related to those browsers?  Or is this the kind of performance to expect with Babylon?
