Abstract
System response and thus interactivity is strictly tied to the frame rate in most virtual reality systems. For complex scenes either the visual quality needs to be sacrificed (e. g. by using a lower level of detail) or the system becomes non-interactive. We suggest that for standard manipulation tasks in virtual environments parting from such a single-frame rate approach is beneficial.
Multi-frame rate rendering uses two (or more) graphics cards to render the interactive parts of the scene on one card and the rest on the other. The results are optically or digitally combined in a single image displayed to the user. This approach significantly
improves the interaction fidelity for medium and large scenes without compromising visual quality. We provide a detailed motivation and an overview of our approach. We argue that modern virtual reality system benefit greatly from multi-frame rate rendering.
