First verify that your exact device, Windows version, graphics driver, game, and rendering API support the FSR 4 path you want to use. In a supported game, start with FSR Quality when image stability matters most, then try Balanced if you need more performance. Add frame generation only after the game already renders roughly 45–60 FPS and the title and driver path support it. No cited source establishes a measured FSR 4 battery-life improvement on handhelds, so treat runtime as a power-profile and game-load result that you must measure on your own device.
Check whether FSR 4 is actually available on your handheld
A settings guide is useful only after the feature path is confirmed. “FSR 4” can refer to AMD’s machine-learning upscaling and frame-generation features, an older FSR implementation exposed by a game, or AMD Software’s driver-upgrade route. Those paths have different hardware, operating-system, API, and integration requirements.

Hardware and platform requirements in AMD’s documented FSR 4 implementation
AMD GPUOpen’s FSR 4.0.2 overview lists Radeon RX 9000 Series and newer graphics, Windows 10 or Windows 11, and DirectX 12 for the documented implementation. That compatibility table describes the implementation on supported Radeon hardware; it is not proof that every handheld APU qualifies.

A planned handheld rollout is not current support
Windows Central reported translated remarks from AMD Senior Vice President and General Manager of Computing and Graphics Jack Huynh saying: “We will expand the machine learning and AI-based FSR 4 technology, which was preemptively introduced in existing external graphics cards, to the entire product lineup by the end of this year, including APUs, gaming laptops, and handheld devices. We plan to respond in two directions: existing APUs and launching new product lines.” The report describes an intention, not a completed rollout. It does not provide a final handheld model list, released driver, operating-system matrix, or validated settings for each device. Read the report at Windows Central, then confirm support in AMD Software and the game itself.
What a support check should establish
| Check | What must be true |
|---|---|
| GPU and driver | The handheld’s Radeon hardware and installed driver must appear in the current AMD compatibility information for the feature you intend to use. |
| Operating system | The documented FSR 4.0.2 path lists Windows 10 or Windows 11. |
| Graphics API | The driver-upgrade route is documented for DirectX 12 games. Vulkan titles are excluded from that route. |
| Game integration | The game either natively exposes ML-based FSR upscaling or meets AMD’s driver-upgrade conditions for an FSR 3.1 or newer integration. |
| Frame-generation path | For ML-based frame generation through AMD Software’s upgrade route, AMD specifies a game using FSR 3.1.4 or newer with frame generation. |
The support details and supported-title information can change. AMD’s official setup and supported-game guidance is the authority to check after a driver or game update.
Quality or Balanced: choosing the first preset
ASUS ROG’s handheld guidance says, “FSR Quality and Balanced are great places to start when trying to get a few extra frames.” That is a starting rule, not a benchmark showing that one mode wins on every screen, game, or APU.
| Preset | Use it first when | What to inspect on the handheld display |
|---|---|---|
| Quality | Fine detail, text, foliage, distant geometry, and temporal stability matter more than obtaining the largest possible frame-rate increase. | Look for edge stability during camera movement, readable HUD text, foliage shimmer, and ghosting behind moving objects. |
| Balanced | The game is close to your refresh-rate or frame-time target and Quality does not leave enough headroom. | Check whether additional softness, shimmering, or reconstruction artifacts are acceptable at the handheld’s native resolution. |
Start with the game’s native FSR 4 option when it has one. Select Quality, play the same demanding scene for several minutes, and then switch to Balanced without changing any other setting. Compare motion, distant detail, UI clarity, and sustained rendered FPS rather than judging a still screenshot alone.
Some games also expose Performance or Ultra Performance modes. The cited handheld guidance does not provide controlled FSR 4 measurements for those modes, so do not label them a universally superior battery or frame-rate choice. Use them only when the game’s workload and the display make the image acceptable, and record the exact mode if you publish your own results.
Set up native FSR 4 integration
Native integration is the simplest path because the game controls the upscaler and can expose its supported options directly.
- Update the handheld’s graphics driver through the manufacturer’s supported Windows update process or AMD Software. Record the driver version before testing.
- Install any game update that adds or updates FSR support. Check the game’s graphics menu for an ML-based FSR or FSR 4 entry rather than assuming an older “FSR” label means FSR 4.
- Confirm that the game is running through a supported API. AMD’s documented FSR 4 driver-upgrade path is for DirectX 12; a native implementation may have its own requirements, which the game developer should state.
- Choose FSR Quality first. Keep resolution, texture quality, sharpening, frame cap, refresh rate, brightness, and power mode unchanged while you establish a baseline.
- Play a repeatable scene for several minutes. Note the rendered FPS before any frame generation, visible artifacts, fan behavior, and the handheld’s power mode.
- Move to Balanced only if Quality misses your target or produces unstable frame times. Recheck text, thin geometry, particle effects, and camera pans after the change.
Do not compare one preset at 15 W with another at 25 W and call the difference an FSR result. A power-profile change can alter both performance and battery drain independently of the upscaler.

Use AMD Software’s driver-upgrade route only when its conditions match
AMD says some games natively integrate ML-based FSR upscaling, while other supported games can use AMD Software’s driver upgrade. The route is not a universal compatibility layer.
Conditions AMD specifies
- The title must be a supported game with a signed FSR 3.1 DLL.
- The documented route targets DirectX 12 games.
- Vulkan games are not compatible with this driver-upgrade feature.
- Some non-standard FSR integrations are excluded.
- ML-based frame generation through the route requires a game with FSR 3.1.4 or higher and frame generation.
AMD describes the route and its limitations in its FSR 4 driver-upgrade article. Its supported-game count was stated as “over 85 games” at the time of that post; that is a dated list, not a permanent promise.
Practical setup sequence
- Open AMD Software and look for the FSR upscaling or driver-upgrade control for the installed game.
- Enable the FSR upscaling toggle only if the game appears on AMD’s current supported-title list and meets the API and signed-DLL requirements.
- In the game, select FSR 3.1 when the menu offers that version. Do not select an older or unrelated upscaler and assume the driver feature will replace it.
- Launch a repeatable scene and verify that the game is using the intended mode. If the option disappears, the game updates, changes API, or fails validation, revert to the native game setting.
- Change one variable at a time and keep a note of the game version, driver, API, resolution, preset, and power profile.
AMD’s technical-preview release notes list driver version 25.10.13.02, Windows 10/11 support, and desktop compatibility names RX 9070, RX 9070 XT, and RX 9060 XT. They also state support for “over 60 games” in that preview context. Those desktop names and the preview count do not establish compatibility for a handheld APU. Consult the release notes for the exact preview scope.
Frame generation: only after the base frame rate is healthy
Frame generation can make motion appear smoother, but generated frames are not the same as additional fully rendered game frames. It can also affect control feel and artifact visibility.
ASUS ROG advises reaching the 45–60 FPS zone before enabling FSR Frame Generation in supported games, or AMD Fluid Motion Frames in other titles. Treat that range as practical guidance from ASUS ROG, not a universal handheld benchmark. Measure the game’s rendered FPS first, with frame generation off.
A safe decision sequence
- Use Quality or Balanced and lower demanding native settings until the game sustains a reasonable rendered frame rate in its heaviest scene.
- Check that the title and platform explicitly support the frame-generation path you intend to use.
- Enable frame generation and inspect camera pans, fast turns, UI movement, hair, foliage, particles, and objects crossing the screen.
- Compare controller responsiveness with frame generation off. If input feels delayed or artifacts are distracting, disable it even if the displayed FPS number is higher.
- Keep generated FPS separate from base rendered FPS in notes or charts. A displayed figure that includes generated frames must be labeled as such.
AMD’s driver-upgrade instructions tie ML-based frame generation to FSR 3.1.4-or-newer integrations. A game that merely contains an older FSR label should not be presented as eligible.
Battery life depends on the whole power profile
FSR reduces the internal rendering workload in many use cases, but the cited sources do not quantify a handheld-runtime gain for FSR 4, Quality, Balanced, or any other preset. CPU load, frame caps, display brightness, refresh rate, cooling, game engine behavior, and the device’s wattage setting can outweigh any upscaling effect.

Ally power-mode guidance
ASUS ROG describes the Ally’s 17 W Performance Mode as a balance between performance and battery life. It also says supported default game profiles aim to balance performance with efficient power use. ASUS ROG’s examples can reach 45–60 FPS or higher depending on model and game, but that statement is not an FSR 4 benchmark and cannot be generalized to every handheld.
If a game already exceeds 60 FPS, testing a lower power profile may make more sense than raising the upscaler to an aggressive mode. Keep the profile fixed while comparing Quality and Balanced; otherwise you cannot tell which change affected frame time or drain.
How to measure your own runtime
- Charge the handheld to the same starting percentage for each run and use the same battery-health conditions.
- Lock brightness, refresh rate, volume, Wi-Fi state, overlays, and background applications.
- Use the same game build, save point, resolution, graphics settings, frame cap, and power mode.
- Run a repeatable scene for a fixed duration with FSR disabled, then repeat with Quality, and finally with Balanced.
- Record average and 1% low rendered FPS, battery percentage consumed, device temperature if available, and visible artifacts.
- Repeat each condition enough times to expose normal variation. Report the handheld model, driver, Windows version, game version, resolution, preset, and wattage mode with any result.
This protocol produces a device-specific observation. It does not turn one handheld’s runtime into a universal FSR 4 battery claim.
Image-quality checks that matter on a small screen
Handheld displays make some reconstruction errors less obvious at normal viewing distance, but high pixel density, a bright scene, or a close viewing distance can reveal them. Check moving footage rather than a paused frame.
- Fine geometry: wires, fences, foliage, hair, and stair rails can shimmer when temporal information is insufficient.
- Text and HUD elements: examine small fonts, maps, subtitles, and inventory icons while moving the camera.
- Disocclusion: watch objects revealed as the camera moves past a wall or character for ghost trails.
- Particles and transparency: smoke, rain, sparks, glass, and foliage can expose instability.
- Dark scenes: inspect shadow edges and thin highlights, where softness and flicker are easiest to notice.
- Motion clarity: compare a controlled pan at the same refresh rate and frame cap before judging a preset.
Sharpening can change perceived detail, so keep it constant during a Quality-versus-Balanced comparison. A sharper image is not necessarily a more accurate reconstruction.

A repeatable handheld tuning workflow
Use this order to avoid confusing an FSR setting with a separate system change.
- Verify eligibility. Confirm GPU, Windows version, driver, API, game integration, and supported-title status.
- Establish a native baseline. Record rendered FPS, frame-time consistency, resolution, refresh rate, power mode, and battery percentage in a demanding scene with frame generation disabled.
- Select Quality. Check image stability and whether the game meets your target without changing the power profile.
- Test Balanced. Repeat the same scene and compare motion, text, thin geometry, and sustained frame time.
- Choose the lower mode only when its image cost is acceptable. Do not use a higher displayed FPS number as the sole criterion.
- Test frame generation last. Use it only when the title and driver path support it and the base rendered FPS is already in a sensible range.
- Measure power separately. Keep brightness, refresh, and wattage constant for preset comparisons; then run a separate battery test if runtime is important.
- Document the result. Include handheld model, APU/GPU, Windows version, driver, game build, API, output resolution, FSR mode, frame-generation state, frame cap, and power profile.
Troubleshooting common failures
The FSR 4 option is missing
Check whether the game natively supports ML-based FSR, whether the driver is current, and whether your hardware appears in AMD’s current compatibility information. A game may support an older FSR version without supporting FSR 4. A planned handheld rollout does not activate the feature automatically.

AMD Software does not offer the driver upgrade
Verify that the game is DirectX 12, uses the required signed FSR 3.1 DLL, appears on AMD’s supported-title list, and does not use an excluded non-standard integration. Vulkan titles are not supported by this route. Game updates can also change the integration and remove eligibility.
Frame generation looks smooth but controls feel poor
Turn it off and compare controller response at the same base settings. Generated frames can raise the displayed cadence without providing the same input responsiveness as additional rendered frames. Keep the mode disabled if the control trade-off is unacceptable.
Balanced looks worse than expected
Inspect a moving scene at the handheld’s native output resolution. If text, foliage, or thin geometry becomes unstable, return to Quality and recover performance through a lower-cost graphics option, a frame cap, or a different power profile rather than assuming the upscaler must be pushed further.
Battery drain is unchanged after enabling FSR
That result is plausible. The cited material contains no controlled handheld battery figure, and the game may be CPU-limited, capped by refresh rate, or dominated by display and system power. Repeat the fixed-scene protocol before drawing a conclusion.
What is known—and what is not—for current handheld buyers
AMD’s technical-preview documentation names desktop RX 9070, RX 9070 XT, and RX 9060 XT products, not a validated handheld APU list. AMD’s GPUOpen article documents FSR 4.0.2 requirements around RX 9000 Series and newer, Windows 10/11, and DirectX 12. AMD’s feature page separately describes broader RX 7000 and RX 9000 ML-upscaling availability and a stated RX 6000 roadmap for 2027. These statements describe different support scopes; they should not be collapsed into “FSR 4 works on every Radeon handheld.”
The ASUS ROG Xbox Ally X is an example of a Windows gaming handheld, but the cited material does not establish that this model already has FSR 4 support. Confirm the exact driver, game, API, and integration before promising a preset for it or any other handheld.

For a personal comparison, publish the complete test conditions rather than a single “best” number. The meaningful axes are image quality and temporal artifacts on the actual screen, sustained rendered FPS before generated frames, control responsiveness with frame generation, and power draw or runtime under the same scene and profile.
Bottom line for choosing a preset
Eligibility comes first. If the game and handheld genuinely support the FSR 4 path, use Quality as the image-first baseline and Balanced when you need additional headroom and accept more reconstruction softness or shimmer. Keep frame generation off until the game already renders approximately 45–60 FPS and the title supports the required implementation. Select the power profile separately, and measure battery behavior on the same device rather than quoting an unverified FSR 4 runtime gain. AMD’s support pages and driver notes remain the place to recheck compatibility as handheld support evolves.
