Today, AMD is soft-launching its latest suite of graphics and performance-enhancing tech, FSR Redstone — and it might take a second to wrap your head around. It certainly did for me.

The good news is that in just three months, AMD has more than doubled the number of games that support the flagship machine-learning version of its upscaling tech, FSR4, to over 200 games in all, and it’s launching ML-based frame generation (yes, “fake frames”) for over 30 titles too. You should be able to find full game lists here sometime today. Both techniques can dramatically increase your framerate while preserving image quality better than FSR 1, 2, or 3 allowed.

The awkward news is that after previously promising “FSR Redstone” would arrive in the second half of this year, AMD is fulfilling that promise primarily by absorbing FSR4 into Redstone. FSR 4 is now “AMD FSR Upscaling (formerly AMD FSR4)”, and Redstone is the umbrella brand for the whole current suite of machine-learning product.

The absorption might be because AMD has only one game to show off its new FSR Ray Regeneration technique — Call of Duty: Black Ops 7, which already launched with it last month — and no games with FSR Radiance Caching, which it now says is available for game developers to bring to their games in 2026.

The slightly confusing news is that you won’t find options for FSR Redstone (or even FSR 4) inside most of your games. You’ll need to have a Radeon RX 9000-series card, as the company’s still saying the machine-learning versions of FSR are exclusive to those. You’ll also need to go into your AMD Software app to enable “AMD FSR Upscaling” and/or “AMD FSR Frame Generation” under the Gaming > Graphics tab, and then you’ll need to enable AMD FSR 3.1 (or occasionally 4) inside the game itself.

That’s because the superior ML versions of these techniques need to be enabled on a per-game basis, but AMD can do it for you (and game developers) in the driver, as long as the games already support FSR 3.1 or FSR 4.

I bought an AMD RX 9070 XT myself after the last stunt Nvidia pulled, but adoption of AMD’s latest hardware is still a little slow. They’veyet to show up in the Steam Hardware Survey, which could mean less than 0.15 percent of today’s PC gamers currently use them — though a generic “AMD Radeon(TM) Graphics” has gained 0.75 percent share on Steam since a year ago.

That could change now that the Radeon RX 9070 and 9070 XT can finally be found at their original promised MSRP prices. They are good cards for that amount of money; here’s our March 2025 review.
