I just upgraded Firefox to version 52.0.2 ESR and I’m experiencing a very low performance in Cesium. I went to Sandcastle to rule out something wrong with my map application.
I opened the star burst sample :
I activated the ShowFramesPerSecond utility:
viewer.scene.debugShowFramesPerSecond = true;
The utility shows an average of 9 fps, that is quite slow for a map with few graphics.
When I was using Firefox version 45.8.0 I was getting from 40 to 50 fps.
Version 52.0.2 supports webgl 1 and webgl2. I tested and Cesium is defaulting to always use webgl 1.
Has anybody else experienced the same issue? If yes, is there a workaround?
My customer is only allowed to use Firefox.
