FSR 4 might stay RDNA 4-first, but AMD is suddenly sounding less allergic to an opt-in experiment.
In a PC World CES 2026 interview, AMD’s software chief, Andrej Zdravkovic, addressed the question that Radeon owners keep asking: whether Redstone will ever turn up on RDNA 3.
Zdravkovic framed Redstone as a stack built around new ML-driven graphics features, with AMD chasing a minimum bar for quality and responsiveness.
That is why AMD has been pinning the full Redstone bundle to RDNA 4, saying it does not want to ship features that miss the target and make the result worse.
PCWorld’s, Adam Patrick Murray was not buying the corporate answer and pushed on why AMD will not simply let users test FSR4 on older GPU series.
Zdravkovic said AMD is not against modders who hack pieces of Redstone onto older cards, which is a polite way of saying, knock yourselves out, just do not ring support.
He said a formal beta track for RDNA 3 is “not planned today”, but he reacted positively to the idea and asked for suggestions on how to pitch it as an “opt-in experiment”, with “clear expectations”.
That is where an “FSR4-lite” path starts to look plausible, with AMD shipping a clearly labelled experimental track for RDNA 3 that enables what works acceptably and leaves the rest switched off.
It would give users a choice, keep it official enough to avoid dodgy downloads, and still let AMD keep the big headline features parked on RDNA 4.
Nvidia is the obvious yardstick, with newer super-resolution models pushed across RTX generations, while heavier frame-generation modes remain tied to newer cards.
