Tonight at NVIDIA's event in Texas, the company showed off some new tools that should help developers make VR experiences even more realistic. CEO Jen-Hsun Huang said its VR Works suite of APIs is getting a "major" upgrade, with the ability to connect haptic controllers to its PhysX physics engine for more realistic feedback, and the "world's first real time physically modeled acoustic simulator." As he described it, the audio engine works on top of the optics API to help it match what you can see. Sight, sound, physics and touch are all enhanced with its new Pascal-based GPUs, and NVIDIA says game developers are already working on implementing the new effects.
