[[Multi-resolution shading]] or '''multi-res shading''' is a [[VR]] rendering [[technology]] introduced by part of the [[Nvidia]]'s [[Gameworks GameWorks VR]]. In multi-res shading, the rendering accounts for the distortion caused by the lenses of the [[HMD]]. It will not render the parts of the image that the user will not see due to the distortion. Multi-res shading improves performance without sacrificing image quality.
Normally, an image on a screen, rendered by [[GPU]], is flat. When the lenses in the HMD distorts the flat image, there is an extra process to "de-distort" the image before it is passed through the lenses and onto your eyes. Because of this, a significant percent of the flat image never makes to your eyes. Multi-res shading does not render the entire flat image. Instead it renders the distorted image directly, saving the processor from rendering a significant number of pixels.
