Nvidia has created a new set of tools and utilities that it has bundled together in the form of Nvidia DesignWorks VR.
DesignWorks VR offers APIs, libraries, and other features that have been created Nvidia to enable both virtual reality headset and application developers to create amazing VR experience for the range of new hardware that is becoming available.
VR SLI provides increased performance for virtual reality apps where multiple GPUs can be assigned a specific eye to dramatically accelerate stereo rendering. As part of Designworks VR, VR SLI is available both in DirectX and OpenGL
Multi-Res Shading is an innovative new rendering technique for VR whereby each part of an image is rendered at a resolution that better matches the pixel density of the warped image. Multi-Res Shading uses Maxwell’s multi-projection architecture to render multiple scaled viewports in a single pass, delivering substantial performance improvements.
Warp & Blend API’s provide application independent geometery corrections and intensity adjustments across entire desktops to create a seamless VR CAVE environments. Warp & Blend API’s enable all the above adjustments for prestine image quality without introducing any latency.
GPU Affinity provides dramatic performance improvements by managing the placement of graphics and rendering workloads across multiple GPU’s.This provides developers fine grain control to pin OGL contexts to specific GPU’s
NVIDIA provides various synchronization techniques to prevent tearing and image misalignent while creating one large desktop that is driven from multiple GPU’s or clusters. Various technologies like Frame Lock, Stereo Lock, Swap Groups & Swap Barriers are available to help developers design seamless and expansive VR CAVE & Cluster environments
NVIDIA’s GPU Direct for Video technology enables low latency video transfers to and from the GPU enabling developers to seamlessly overlay video and graphics into VR environments
