I did some tests with the great online demo http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/index.html regarding CPU/GPU resources consumption. I have the impression cesium is using a lot of GPU + CPU when the application stands still (no navigation and no dynamic data, just watching the cesium globe on the screen, without interacting with it). I also compared it to Google Maps 3D view in WebGL, wich uses NO ressources when in idle mode
Is there some fine tuning to do in order to improve the resource consumption? Are there any plan of optimization?
Here are the result of my tests:
my graphic card:
The cesium globe using 40% GPU and 20% CPU:
Google map example, less than 5% of CPU usage and 0% GPU.
