AMD FSR Could Get Multi-Frame Generation for Higher FPS Gains

AMD may be preparing a major upgrade to its FidelityFX Super Resolution technology, even as FSR 4.1 has only recently arrived. Early SDK references suggest the company is exploring multi-frame generation (MFG), a feature that could significantly increase performance flexibility in future updates.

FSR Could Get Multi-Frame Generation

According to newly spotted FidelityFX SDK entries, AMD is working on support for multi-frame generation. This would allow developers to go beyond the current ~2x frame generation limit and define custom scaling ratios.

The feature appears through a new option labeled IADLX3DFidelityFXFrameGenUpgradeRatioOption, which gives developers more control compared to fixed presets. This change signals a shift toward more dynamic and customizable performance scaling.

Potential RDNA 4 Hardware Limitation

While AMD has not officially confirmed the feature, early indications suggest that multi-frame generation could be limited to RDNA 4 GPUs. This would mirror NVIDIA’s approach, where similar technology is restricted to newer architectures like the RTX 50 series.

If true, older Radeon GPUs may not receive official support, which could impact adoption across existing users.

Performance Gains vs Latency Trade-Off

Multi-frame generation could deliver higher frame rates, especially in demanding titles. However, generating additional frames introduces latency, which may affect responsiveness in fast-paced games.

To address this, AMD is expected to rely on its latency reduction technologies. Radeon Anti-Lag 2, which may be rebranded to FSR Latency Reduction 2.0, aims to minimize input lag and balance performance with responsiveness.

AMD vs NVIDIA: Closing the Gap

NVIDIA already offers multi-frame generation with dynamic scaling tied to monitor refresh rates. AMD’s approach appears to focus on flexibility through developer-defined ratios, which could provide more granular control.

Whether AMD can match NVIDIA’s latency handling will likely determine how competitive this feature becomes.

FSR 4.1 Already Available to Developers

While multi-frame generation remains unconfirmed, FSR 4.1 is already available via SDK. Developers can begin integrating the latest improvements immediately, setting the stage for future enhancements like MFG.

Overall, AMD is clearly pushing to expand FSR’s capabilities. If multi-frame generation arrives, its success will depend on hardware support and how effectively latency is managed.
