VRWorks
GameWorks VR is a suite of virtual reality technologies developed by Nvidia to tackle high-performance VR rendering. It contains a set of APIs, libraries and features that enable both hardware manufacturers and software developers to create ideal VR experiences.
Features
VR SLI
VR SLI increases the performance of VR Apps by assigning 1 or more GPUs to each eye when stereo rendering (creating a different image for each eye). Because VR utilizes 2 independent views, developers can parallax the rendering across 2 different GPUs then combine the images into a single frame in the HMD. It allows the app to have higher fps or graphical settings. Additionally, VR SLI API allows developers to scale the entire system to more than 2 GPUs. Developers can split up the rendering anyway they want across any number of GPUs they desire.[1]
