NVIDIA VRWorks 2016 Technology Updates Explained

On May 6, NVIDIA revealed the first gaming GPU based on their new Pascal architecture – the NVIDIA GeForce GTX 1080. The GeForce GTX 1080 not only boasts the latest Pascal architecture, it is also fabricated on the new 16 nm FinFET process technology and uses the new GDDR5X memory.

Although we were not in Austin, Texas for the official launch, NVIDIA invited us to an exclusive tech briefing in Bangkok on May 20th. While these hardware specifications are well-known by now, this was a technical briefing that would give us greater insights into the other new technologies that are being introduced with the GeForce GTX 1080.

NVIDIA VRWorks 2016 Explained

NVIDIA brought in the big guns for the tech briefing and demonstration – Nick Stam (NVIDIA Senior Technical Marketing Director), Jeff Yen (NVIDIA Senior Technical Marketing Manager) and John Gillooly (NVIDIA Technical Marketing Manager). We will be posting a series of videos of their presentations, divided into topic-specific chunks. Today, we are going to look at the new NVIDIA VRWorks 2016 technology updates.

 

NVIDIA VRWorks 2016 Explained

In this 11 minute video, Nick Stam talks about the higher requirements for VR gaming and the new path-traced audio capabilities being introduced as NVIDIA VRWorks Audio. Then Jeff Yen steps in with the NVIDIA VR Funhouse demo. Check it out!

 

NVIDIA Pascal-Specific VRWorks Features

The new Simultaneous Multi-Projection architecture of the NVIDIA Pascal-based GPUs will be able to tackle two unique performance challenges that virtual reality creates – Lens Matched Shading and Single Pass Stereo.

Lens Matched Shading improves pixel shading performance by rendering more natively to the unique dimensions of VR display output. This avoids rendering many pixels that would otherwise be discarded before the image is output to the VR headset.

Single Pass Stereo turbocharges geometry performance by allowing the head-mounted display’s left and right displays to share a single geometry pass. We’re effectively halving the workload of traditional VR rendering, which requires the GPU to draw geometry twice — once for the left eye and once for the right eye.

Both techniques allow developers to increase performance and visual detail of their VR applications. Combined with the performance of GTX 1080 GPUs, Simultaneous Multi-Projection delivers a dramatic 2x VR performance improvement over the GeForce GTX TITAN X.
