I was there folks, I was there. In May of this year, AMD announced a massive new update to its upscaling tech, giving us our first glimpse of FSR 4 "Redstone" which was said to be bringing a whole host of machine learning-based improvements.
One of the key features is the addition of Ray Regeneration, which, much like Nvidia's Ray Reconstruction tech, is said to be capable of regenerating inaccurate pixels to prevent the gritty, noisy mess that can surround some ray traced lighting effects. The Redstone update was supposed to be making an appearance at some point this year, but it's been so long since we'd heard anything about it, I'd nearly forgotten it existed.
