AMD’s next-generation GPUs, namely Navi and beyond, may utilize new shading techniques to deliver better performance in games. In a patent filed by AMD back in 2017, which was recently made public, it is stated that AMD was investing resources in developing advanced GPU shading technologies, namely, Variable Rate Shading (VRS) as found by Tomshardware.

The said feature isn’t something new in the industry as NVIDIA has already introduced Variable Rate Shading on their Turing architecture-based graphics cards. NVIDIA explains that their VRS (Variable Rate Shading) technology increases rendering performance and quality by applying varying amounts of processing power to different areas of the image.
