Last week, AMD released a major update to AMD Software: Adrenalin Edition, codenamed “Redstone”, the driver package for Radeon graphics cards. Compared to earlier versions, it now uses AI to improve performance and image quality—not only for FSR 4 upscaling, but it also adds other AI-driven technologies: FSR Frame Generation, FSR Ray Regeneration, and FSR Radiance Caching. Let’s take a look at how to get frame generation up and running.
What AMD has said about the individual technologies is discussed in the initial article AMD FSR Redstone is official: using AI for higher image quality published at launch.
Today, we’ll focus more closely on one of the new features—the improved frame generation.
Only on RX 9000 Radeons
Some time ago, there was speculation that certain AMD technologies using AI could run on older Radeon generations with the Redstone package. There are hacks that allow them to be injected into games and made to work to some extent. For now, however, this is not the case.
According to AMD, AI-based technologies currently work only on the latest-generation Radeons based on the RX 9000 architecture. Which technologies are supported by which architectures is shown in the table below:
| AMD FSR feature | AMD RDNA 1, 2, 3 and 3.5 | AMD RDNA 4 |
|---|---|---|
| AMD FSR Upscaling (ML) | ✓ | |
| AMD FSR Upscaling (analytical, non-ML) | ✓ | ✓ |
| AMD FSR Frame Generation (ML) | ✓ | |
| AMD FSR Frame Generation (analytical, non-ML) | ✓ | ✓ |
| AMD FSR Ray Regeneration (ML) | ✓ | |
| AMD FSR Radiance Caching (ML) | ✓ |
AMD FSR Frame Generation
FSR Frame Generation is used to insert a generated, interpolated frame between two frames rendered by the game. In FSR 3.1, this was a simpler analytical interpolation. On Radeon RX 9000 cards, the generated frame is enhanced by AI using two consecutive frames and additional data (such as motion vectors).
The improved FSR Frame Generation algorithm is based on a pair of consecutive frames, the scene’s depth map, and motion vectors. To these it adds an estimate of optical flow, i.e. information about how individual parts of the image move between frames. A neural network first estimates the motion and appearance of each pixel from this data, then combines these predictions with classic reprojection based on motion vectors and assembles a new intermediate frame from the result.
The model does not only determine where a pixel moves, but also what color it should have, because it takes into account temporal context (both the previous and the following frame) as well as motion information. The goal is for the inserted frame to visually connect to both neighboring frames, preserve object shapes, and reduce artifacts such as ghosting, edge breakup, or flickering during fast motion.
In fast-paced games, such as racing titles like F1 25, the new ML-based version of Frame Generation improves smoothness and image stability at high monitor refresh rates compared to the original frame generation from FSR 3.1.
For example, you may notice artifacts on road shadows that were created during frame generation because the road under the car moves while the shadows remain fixed on the asphalt. FSR Redstone can correct this issue more effectively.
As with FSR 4 upscaling, there are two ways to use it in games: either developers integrate it directly into the game engine via the SDK, or it is enabled through AMD Software drivers and then activated in supported games that have implemented FSR 3.1 with Frame Generation. Thanks to this, the following titles already support ML-based frame generation at driver release:
| ARC Raiders | F1® 25 | Mafia: The Old Country | Squad |
| Black Myth: Wukong | Farming Simulator 25 | Marvel Rivals | THE FINALS |
| Call of Duty®: Black Ops 7 | God of War Ragnarök | No More Room in Hell 2 | The Last Caretaker |
| Cash Cleaner Simulator | Grand Theft Auto V Enhanced | Project Motor Racing | The Talos Principle: Reawakened |
| Cronos: The New Dawn | Hell is Us | Qanga | Titan Quest II |
| Cyberpunk 2077 | Hogwarts Legacy | Rem Survival | Winter Survival |
| Deathground | INDUSTRIA 2 (demo) | Ships At Sea | Wreckfest 2 |
| EXFIL | Keeper | SpongeBob SquarePants: Titans of the Tide | Wuthering Waves |
Titles highlighted in bold should have support for the new generation of Frame Generation integrated directly into the game; for the others, it should activate automatically if you enable the corresponding toggle in the drivers.
However, the driver toggle does not add frame generation to games in which developers did not integrate support for FSR 3 Frame Generation. It therefore does not replace the AFMF (AMD Fluid Motion Frames) technology for generating intermediate frames in games that do not offer FSR Frame Generation.
