Is AMD preparing FSR 4.1?
ASRock either knows about AMD’s plans or did not check whether such an FSR version even exists.
First, let’s start with the most obvious question: does FSR 4.1 exist? Technically, the latest version is 4.0.2. AMD recently released FSR Redstone Ray Regeneration technology alongside Call of Duty: Black Ops 7, so it is possible this is how AMD is now referring to this technology as a whole. That is the theory. In reality, we could not find any reference to FSR 4.1 on any official site.
This version was mentioned by ASRock in a tweet about this tech, claiming it is already supported by RX 9070 XT cards:
Not just graphics — this GPU thinks faster than you do.

Our theory is that someone at ASRock either knows what AMD will soon launch for other games, or this is just a mistake. Their tweet links specifically to the Taiwanese version of their website, and there we can find such notes:
The “4 1 ” is obviously not 4.1, but perhaps someone copied the text, added a dot from the annotation, and created some confusion in ASRock marketing.
In reality, it would make sense for FSR 4 with Redstone RR to be called 4.1. The full update with all four Redstone technologies could then be released as FSR 5. AMD might not want to call it 5 yet because they do not know what to expect from DLSS 5, and they seem to want some level of parity in naming and features.
