Notes de l'éditeur
- We talk a lot about VR in the context of gaming and traditional pro/design apps. VR is the next app and computing platform. The next smartphone. Opportunity well beyond gaming and traditional pro markets
- Virtual reality is extremely demanding with respect to rendering performance. Both the Oculus Rift and HTC Vive headsets require 90 Hz, a very high framerate compared to gaming on a screen. We also need to hit this framerate while maintaining low latency between head motion and display updates. Mike Abrash at Oculus has done some research on this, and his results show that the motion-to-photons latency should be at most 20 milliseconds to ensure that the experience is comfortable for players. The problem is that we have a long pipeline, where input has to first be processed and a new frame submitted from the CPU, then the image has to be rendered by the GPU, and finally scanned out to the display. Each of these steps adds latency. Traditional real-time rendering pipelines have not been optimized to minimize latency, so this goal requires us to change how we think about rendering to some extent.

- NVIDIA has created a VR SDKs for headset and HMD developers that improves performance, reduces latency, improves compatibility, enables immersive environments, and accelerates 360 video broadcast.

- And speaking of Summiting Everest – let me leave you with a small teaser. This isn’t a photograph, but rather a first look screenshot from a VR experience from Icelandic VR developer, Solfar, which we will be integrating GameWorks VR with. Stay tuned for an announcement and more details from Solfar tomorrow! We are excited to be working with Icelandic based Solfar to bring -- stay tuned for an exciting announcement from Solfar on Tuesday.
