set
Enable or disable eager loading of tiles that appear on screen during gestures or animations, while the gesture or animation is still in progress. By default this is enabled to improve responsiveness, but it can result in tiles being loaded and discarded more rapidly than necessary and reduce the animation frame rate on old/cheap devices. Disable this on older devices if you see poor performance. Tiles will then be loaded only when gestures and animations are completed.
Parameters
eager
true to enable loading during gestures, false to delay loading until gestures end
