AMD just gave us our first glimpse of FSR 4’s ‘Redstone’ update, with a host of machine learning-based improvements

AMD just gave us our first look at a significant update to FSR 4, codenamed “Redstone.” The new update is due to arrive in the second half of this year, and looks like something of a catch-up phase to counter Nvidia’s recent efforts with DLSS.

Top of the list is Neural Radiance Caching, which AMD says “continually learns how light bounces in a scene to predict and store indirect lighting”. FS4 Redstone will also feature machine learning-enhanced ray regeneration, which it says is capable of regenerating inaccurate ray traced pixels.

Oh, and a new ML model will be added to its Frame Generation tech, which apparently uses temporal and spatial awareness to generate frames. Phew.

And a very shiny AMD-red car, to demonstrate it, of course. The news comes as a bit of a last-minute surprise, but yours truly has been typing furiously on his laptop at the press conference to catch you up. Technical details are still thin on the ground, but it all sounds good on paper, at least.
