AMD FSR 3 FidelityFX Super Resolution Technology Detailed: 2x The FPS With Frame Interpolation, Easy To Integrate In Existing FSR 2 Titles
AMD has detailed its FSR 3 FidelityFX Super Resolution technology at GDC 2023, giving us a taste of what's coming to the gaming scene.

In an early look provided to GDC attendees, AMD revealed that FSR 3 FidelityFX Super Resolution will leverage from:
- Motion Vectors and AMD Fluid Motion to produce interpolated frames
- Good motion estimation is key for interpolation
- Additional internal information from FSR 2 can be leveraged
During the last part of our temporal upscaling session, we also revealed some early information about FSR 3 and talked about the benefits and challenges in development.
With FSR 2 we’re already computing more pixels than we have samples in the current frame, and we realized we could generate even more by introducing interpolated frames. This has allowed us to achieve up to a 2x framerate boost in the process.
Frame interpolation is more complex, as there are several challenges:
However, there is good news!
- We can’t rely on color clamping to correct the color of outdated samples.
- Non-linear motion interpolation is hard with 2D screen space motion vectors, which is why we recommend at least 60fps input.
- If the final frames are interpolated, then the UI and all post-processing will also need to interpolated.
- There’s a high probability there will be at least one sample for every interpolated pixel.
- There’s no feedback loop as the interpolated frame will only be shown once – any interpolation artifact would only remain for one frame.
