It depends on what one means by "improve". Generally, until computer graphics technology improves much beyond what is currently available, when it comes to large datasets we will always have to choose between quality and time. If we want a higher quality it will take more time to load, more time to render, and therefore a less interactive experience. If we want faster rendering we need to sacrifice quality. But first, it is important to remember that the purpose of the 4D viewer is to provide a way to manually interact with 3D data, which requires a certain level of interactivity and therefore a reasonable rendering frame rate. If our intention is to produce a high-quality screenshot or animation then we should use the HD Screenshot or Storyboard tools.

So what are the options available?
