[[VRWorks]], formerly known as '''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 engine and [[HMD]] developers to create the ideal [[VR]] experiences.

===VR SLI===
[[VR SLI]] increases the performance of [[VR Apps]] by assigning 1 or more [[GPU]]s 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.<ref name="GameWorks_VR_Site">https://developer.nvidia.com/virtual-reality-development</ref>
===Multi-resolution shading===
[[Multi-resolution shading]] renders different parts of the image with different resolutions to better match the [[pixel density ]] of a warped image. When a flat image is viewed from the lenses of an HMD, the image is distorted. The processor has to perform an additional task that "de-distort" or warps the image. The warp pass compresses the edges of the image, reducing pixels there. Multi-res shading renders a warped image directly, keeping full resolution in the center of image while reducing the resolution of the edges of the image.<ref name="GameWorks_VR_Site">https://developer.nvidia.com/virtual-reality-development</ref>
===Context Priority===
===Front Render Buffering===
[[Front Render Buffering]] allows the GPU to render directly to the front buffer to reduce latency.<ref name="GameWorks_VR_Site">https://developer.nvidia.com/virtual-reality-development</ref>
