Variable Rate Shading (VRS) is a new DX12 feature introduced recently, that can be used to control shading rate. To be more precise, it is used to reduce shading rate, as opposed to the Multi Sampling Anti Aliasing (MSAA) technique which is used to increase it. When using MSAA, every pixel gets allocated multiple samples…
