Cesium Earth entity path quality

I have developed an application, using the Cesium Earth library.

The problem is, the drawn line (entity path) has very low quality, it's not smooth. How to make it better?

  viewer = new Cesium.Viewer('cesiumContainer', {
    imageryProvider: false,
    shadows:true,
    skyAtmosphere: false,
    geocoder: false,
    shouldAnimate:true,
    clockViewModel: new Cesium.ClockViewModel(clock),
    imageryProviderViewModels: imageryViewModels,
    requestRenderMode : true
  });

entity[i] = viewer.entities.add({              
            path:{
               leadTime:leadTime,
               trailTime:trailTime,
               width:1.5,
               material: color,
               resolution:10
            }
});

satellite[id].position.setInterpolationOptions({
         interpolationDegree : 10,
         interpolationAlgorithm : Cesium.HermitePolynomialApproximation 
});
