In a post on GPUOpen, a site for game and graphics developers, AMD may well have let slip that it plans to take a leaf from Nvidia's book of rendering tools by including a ray tracing denoiser system in its next generation of FSR. And just as important, it will use an AI neural network to do it all.
Unless you've been firmly sticking with an old graphics card and consciously ignoring every GPU development in the past six years, you'll know that AMD, Intel, and Nvidia have all been furiously busy implementing techniques to improve ray tracing performance and visual quality.
