For most AMD Radeon owners, the best NeuralHub alternative is the option already exposed by the game or driver: use AMD FSR 3 or FSR 3.1 when the game natively supports it, and use AMD Fluid Motion Frames (AFMF) when you need driver-level frame generation in a title without native support. FSR Upscaling and frame generation are separate functions, so you can often combine them. Newer machine-learning features branded FSR 4 or Redstone are limited to selected Radeon generations and games; an upgrade such as the Radeon RX 9070 XT is only worthwhile if your current card cannot use the feature you want.
No single mode wins every game. Your Radeon generation, current driver, game API, native support, base frame rate and tolerance for artifacts determine the right choice.

What you are replacing
Upscaling and frame generation improve different parts of the rendering pipeline. Upscaling renders the game internally at a lower resolution, then reconstructs an image closer to your display resolution. Because the GPU shades fewer pixels, it can raise the rendered frame rate, but fine detail, motion stability and temporal artifacts depend on the algorithm and quality mode.

The game still has to render the original frames that provide the motion data. Generated frames can make camera movement look smoother, but they do not provide the same input response as a newly rendered frame. A low base frame rate can therefore feel sluggish even when the displayed counter is high.

NeuralHub is not the only way to combine these techniques on Radeon hardware. AMD supplies a native, game-integrated path through FidelityFX Super Resolution (FSR), and a driver-level path through AMD Fluid Motion Frames (AFMF). The newer FSR 4/Redstone family adds machine-learning components on selected GPUs. These paths overlap, but they are not interchangeable.
Quick comparison of the practical alternatives
| Option | How it runs | Radeon requirement | Functions | Best use | Main limitations |
|---|---|---|---|---|---|
| AMD Fluid Motion Frames (AFMF) | Driver feature managed in AMD Software: Adrenalin | Support varies by current Adrenalin release, API and GPU; AMD’s September 2024 testing covered RX 7900 XTX, RX 7800 XT, RX 7600 XT and Radeon 890M systems | Frame generation only | A game has no native frame-generation option, or you want one switch that can work across supported titles | Driver/API compatibility, possible artifacts, and the need for a healthy base frame rate; it does not supply upscaling |
| FSR 3 / FSR 3.1 frame generation | Integrated into the game by its developer | AMD GPUOpen describes backward compatibility for RDNA 3.5, RDNA 3 and RDNA 2; the title must implement it | Temporal upscaling and frame generation (the game may expose either or both) | A supported game where motion vectors and other game data are available to the algorithm | Availability and quality vary by title; implementation patches and settings matter |
| FSR Upscaling | Game-integrated reconstruction, selected by the player in the graphics menu | Use the FSR version the game supports; newer ML-powered variants have narrower hardware boundaries | Upscaling only | More rendered frames without adding synthetic frames or input latency from frame generation | Lower internal resolution can soften detail or reveal shimmering, especially in aggressive modes |
| FSR 4 / Redstone features | Newer FSR SDK and game implementations | Selected Radeon RX 7000 and RX 9000 products according to AMD’s current technology information; verify the exact game and GPU | Machine-learning upscaling and, where implemented, frame-generation features | Owners of a supported newer Radeon seeking the latest AMD image-reconstruction path | Not a universal driver switch; support is hardware- and game-specific |
| Radeon RX 9070 XT upgrade | Physical GPU upgrade | RX 9000-series hardware | Access to features implemented for that generation, including supported FSR 4 capabilities and frame generation | Your present card cannot access the required FSR generation | Cost, availability and the rest of the system become the limiting factors; launch pricing is not a current quote |
AMD Fluid Motion Frames: the broadest driver-level substitute
AMD describes AFMF as a frame-generation technology intended to increase frame rates and smoothness with minimal image-quality impact. Its defining difference from FSR 3 is where it runs: AFMF is enabled through AMD Software: Adrenalin instead of requiring every game to integrate a new AMD SDK. That makes it useful for games that have no native frame-generation menu.
When AFMF is the right first try
- The game uses a supported API and current Radeon driver, but offers no native frame generation.
- You want to test frame generation without waiting for a developer patch.
- You are comfortable checking the current Adrenalin release notes rather than assuming every game is compatible.
AMD’s September 2024 published testing used Radeon RX 7900 XTX, RX 7800 XT, RX 7600 XT and Radeon 890M systems with Adrenalin 24.9.1. Those examples show the range of Radeon families AMD tested at that time; they are not a promise that every model, API or future driver behaves identically.

- Install a current AMD Software: Adrenalin Edition driver that lists AFMF support for your Radeon and operating system.
- Open AMD Software: Adrenalin Edition and select the Gaming tab.
- Choose the global graphics profile or create a profile for the specific game.
- Turn on the AMD Fluid Motion Frames option when it is available. Some driver releases expose additional AFMF controls, so use the labels shown by your installed version.
- Launch the game through the profile you configured and test a repeatable scene. If the option is unavailable or the game behaves incorrectly, disable it for that profile and check API and driver support before changing other settings.
AFMF’s frame-rate and latency boundaries
AFMF cannot replace a sufficiently fast base render. A generated image is calculated from preceding rendered frames; it does not create new game simulation or reduce the time between your input and the next genuinely rendered frame. Start with a stable base rate that feels responsive, then enable AFMF. A very low or erratic base rate can produce uneven motion, visible interpolation errors or a high displayed number that does not feel equally responsive.
Because AFMF operates outside the game’s renderer, it may have less scene-specific information than an integrated solution. HUD elements, particle effects, rapid camera turns and disoccluded objects are common places to inspect. There is no independent cross-platform latency or image-quality statistic establishing AFMF as universally better or worse than native FSR frame generation, so judge it in the particular game and driver combination you use.
FSR 3 and FSR 3.1: prefer native integration when the game offers it
FSR 3 combines temporal super-resolution with a frame-generation path that the developer integrates into the game’s render pipeline. AMD GPUOpen describes an analytical frame-generation approach with backward compatibility for RDNA 3.5, RDNA 3 and RDNA 2 architectures. When a game exposes FSR 3.x, this is usually the best first recommendation because the algorithm can receive motion vectors, depth data and UI information from the renderer instead of inferring everything externally.
What “up to 2x” means
AMD’s FSR 3 materials state that supported games can deliver up to 2x frame rates. This is an AMD vendor claim and a ceiling for particular workloads, settings and hardware, not a guaranteed result for every Radeon card or title. Your actual change depends on internal resolution, CPU limits, scene complexity, the selected quality mode and whether you measure rendered or displayed frames.
How to configure FSR 3.x in a supported game
- Update the game to the version that includes FSR 3 or FSR 3.1. A title can expose an option only after a patch.
- Open the game’s Graphics, Display or Upscaling menu.
- Select AMD FSR and choose a quality preset such as Quality, Balanced or Performance according to your resolution and base frame rate.
- Enable the separate Frame Generation or FSR Frame Generation switch if the title provides one. Some games let you use FSR upscaling without generation, or generation with a different upscaler.
- Apply the settings, restart the game if requested, and test camera motion, foliage, transparencies and HUD elements rather than relying only on the frame counter.
Native integration is not automatically perfect. Different developers choose different defaults, update their implementation at different times and may expose frame generation only in certain APIs. If FSR 3.1 looks worse than AFMF in one title, that is a title-specific result, not evidence that one technology always wins.
FSR Upscaling and frame generation can be used together
They address separate bottlenecks. FSR Upscaling lowers the number of pixels the game renders; frame generation inserts images between the frames that remain. In a supported game, a common sequence is:
- Choose an FSR quality mode to establish a stable, responsive base frame rate.
- Enable frame generation only after that base rate is acceptable.
- Cap the final displayed rate if your monitor, game engine or driver behaves more smoothly with a ceiling.
- Check for artifacts and input response in demanding scenes.
Combining them is not mandatory. If your base frame rate is already high and you mainly want cleaner detail, use upscaling alone. If the game is resolution-limited but already renders enough frames, generation may add smoothness without changing the internal resolution. If the game is CPU-limited, lowering resolution may deliver little benefit, while generated frames can still increase the displayed count without fixing the CPU bottleneck.
FSR 4 and Redstone: verify the exact Radeon before choosing them
AMD’s current technology information identifies ML-powered FSR availability on selected Radeon RX 7000 and RX 9000 products. GPUOpen documentation describes newer Redstone and FSR SDK components with explicit hardware boundaries. Treat “FSR 4” or “Redstone” as a compatibility question, not a generic synonym for every FSR release.

Checklist for a current Radeon
- Record the exact GPU model, not just “Radeon RX 7000” or “RX 9000.”
- Install the driver version required by the game or feature documentation.
- Check whether the individual game implements the relevant FSR version; a compatible GPU cannot add a missing game integration by itself.
- Confirm the feature is available at your operating-system and API combination.
- Compare the game’s FSR 4/Redstone option with its FSR 3.x and native-resolution modes in the same scene.
For an older Radeon that does not qualify, use the FSR version the game actually exposes or try AFMF where supported. Do not assume a driver update can turn unsupported hardware into an ML-capable part.
Interpreting AMD’s 4.7x example
An AMD technical article published in 2026 reports a 4.7x FPS increase for FSR Frame Generation on an RX 9070 XT test configuration. That is a vendor test result for the stated configuration and workload, not a universal benchmark. It demonstrates the potential of combining a capable GPU, a supported game and the relevant settings; it does not predict your result at a different resolution, quality mode or CPU limit.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When a Radeon hardware upgrade is the real alternative
If your current card cannot access the FSR generation you want, software settings cannot remove that hardware boundary. AMD announced the Radeon RX 9070 XT on February 28, 2025, with a $599 suggested launch price and a positioning around FSR 4, frame generation and Radeon Anti-Lag. That was the launch recommendation, not a current retail price; availability and street prices change, so check live listings before buying.
Who should consider an RX 9070 XT
- You have verified that a target game requires an RX 9000-class feature you cannot use on your present card.
- Your CPU, power supply, case airflow and display resolution are appropriate for a substantially faster GPU.
- You want a hardware path to newer ML-powered FSR implementations rather than a driver-level workaround.
Who should not upgrade solely for a feature label
- Your game already runs at a comfortable base frame rate with FSR 3.x or AFMF.
- The title you play does not implement FSR 4/Redstone, so the new hardware would not expose the desired option.
- Your limitation is CPU simulation, memory capacity, shader compilation stutter or poor game optimization rather than pixel throughput.
Check the exact game list and requirements before treating the RX 9070 XT as a solution. A faster card cannot create a frame-generation integration that the developer did not ship.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesChoosing by situation
The game has FSR 3 or FSR 3.1
Start with the native implementation. Select an FSR quality mode, establish a stable base rate, then test the game’s frame-generation switch. Use AFMF as a comparison only if the native result has unacceptable artifacts or the game exposes a driver-compatible path that behaves better for you.
The game has no native frame generation
Try AFMF if your Radeon, API and current Adrenalin driver are supported. Keep the game’s own upscaler or a supported FSR upscaling mode separate from AFMF; AFMF itself is not an upscaler.
You want maximum responsiveness
Use FSR Upscaling alone, or a native FSR mode without frame generation, and target a high stable rendered frame rate. Synthetic frames can improve perceived smoothness but do not provide the same input timing as rendered frames.
You own a newer Radeon and see an FSR 4/Redstone option
Verify the model and driver first, then compare the ML-powered mode with FSR 3.x in the same game scene. Keep the mode that preserves the detail you care about; the newest label is not a guarantee of the best result in every implementation.
Your Radeon is unsupported for the desired feature
Use the strongest FSR version your game supports, test AFMF if available, or evaluate a GPU upgrade. Do not buy on the basis of a series name alone: support is determined by the exact model, driver and game.
Image-quality, artifact and troubleshooting checks
Inspect the right things
- Fine geometry: wires, fences and foliage reveal reconstruction shimmer or breakup.
- Fast motion: pans and turns reveal frame-generation warping and uneven pacing.
- Disocclusion: objects uncovered by camera movement can expose missing motion information.
- HUD and text: an integrated implementation may handle UI elements differently from a driver-level layer.
- Input response: compare the feel at the same rendered base frame rate, not only the final displayed number.
If the option is missing
- Confirm the game is updated to a build that supports the feature.
- Confirm your exact Radeon model and driver meet the stated requirement.
- Check whether the game is running through a supported graphics API.
- Restart the game after changing the driver profile or graphics API.
- Remove conflicting overlays or third-party frame-rate tools while testing.
If the result stutters or feels delayed
- Disable frame generation and measure the native base rate.
- Lower the FSR quality mode only enough to produce a stable base rate; an unstable aggressive mode can look worse than a slower, steadier one.
- Check for a CPU limit, shader-compilation stutter or background load before blaming the upscaler.
- Compare AFMF with the game’s native FSR frame generation in the same repeatable scene.
What the evidence does and does not establish
AMD publishes capability descriptions and vendor test figures, including the “up to 2x” FSR 3 claim, the 2024 AFMF test hardware list and the 2026 RX 9070 XT 4.7x example. Those figures are useful for understanding intended capability, but they are not a cross-platform ranking. No independent, standardized latency or image-quality statistic establishes a universal winner between AFMF, FSR 3.x and newer FSR variants. The most reliable decision is therefore empirical: match the feature to the game, keep the base frame rate healthy, and inspect motion and responsiveness at your own settings.
Bottom line
Use FSR 3 or FSR 3.1 first when the game natively supports it, because integration gives the algorithm game motion data. Use AFMF when you need driver-level frame generation for a supported game without a native option. Treat FSR Upscaling and frame generation as complementary controls, not competing names. For FSR 4/Redstone, verify the exact Radeon and game; if your hardware is outside the supported boundary, an RX 9070 XT or another compatible upgrade is the durable solution, subject to current pricing and system requirements.
