Silky smooth interactions are critical for providing a natural-feeling application. The devil is in the details, and ill-performant web animations feel awkward, “janky”, and, above all, slow.
Independent rendering allows the browser to selectively offload graphics processing to an additional CPU thread, so they can be rendered with minimal impact to the user interface thread and the overall visible performance characteristics page, such as silk-smooth scrolling, responsive interactions, and fluid animations.
