The data length is about 150000. The time span of the data is about three months. After adding, FPS becomes 2fps. I try to set path resolution (12 * 60 * 60), But It is useless. The same data is added with primitive ，The Performance is so good. About 60Fps.But the data coordinate system is Cesium.ReferenceFrame.INERTIAL.The path changes over time! What should I do?
