[[VR SLI]] is a [[VR]] rendering [[technology]] part of the [[Nvidia]]'s [[GameWorks VR]]. 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>
