	[[Multi-resolution shading]] or '''multi-res shading''' is a [[VR]] rendering [[technology]] part of the [[Nvidia]]'s [[GameWorks VR]]. In multi-res shading, the rendering accounts for the distortion caused by the lenses of the [[HMD]].

[[Multi-resolution shading]] or '''multi-res shading''' is a [[VR]] rendering [[technology]] part of the [[Nvidia]]'s [[GameWorks VR]]. In multi-res shading, the rendering accounts for the distortion caused by the lenses of the [[HMD]]. The center of the image, an area unaffected the distortion, is rendered at high [[resolution]] than the edges of the image, where distortion occurs. Multi-res shading improves performance without sacrificing image quality.

	Normally, an image on a screen, rendered by [[GPU]], is flat. In an HMD, users view the image through lenses that allow the users to focus and increase [[field of view]]. When viewed from lenses, a flat image is greatly distorted. To counter this, the VR runtime software has to perform an extra process to "de-distort" or warp the image before it is passed through the lenses and onto your eyes. Because of this warp process, the edges of the image are compressed and have fewer pixels. Multi-res shading does not render the entire flat image. Instead, it renders the warped image directly, saving the processor from rendering a significant number of pixels.		Normally, an image on a screen, rendered by [[GPU]], is flat.

			Multi-res shading should be used by a game engine developer. It cannot be turned on from the driver directly.

	According to Nvidia engineer [[Tom Peterson]], multi-res shading can save about 50% of the pixel load.<ref>https://www.youtube.com/watch?v=88RnIVcvuRY</ref>		According to Nvidia engineer [[Tom Peterson]], multi-res shading can save about 50% of the pixel load.<ref>https://www.youtube.com/watch?v=88RnIVcvuRY</ref>

[[Multi-resolution shading]] or '''multi-res shading''' is a [[VR]] [[technology]] introduced by [[Nvidia]]'s [[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.
