AMD FSR 3 FidelityFX Super Resolution Technology Detailed: 2x The FPS With Frame Interpolation, Easy To Integrate In Existing FSR 2 Titles

wccftech.com:

AMD has further detailed its FSR 3 FidelityFX Super Resolution technology at GDC 2023, giving us a taste of what's coming to the gaming scene.

At GDC 2023, AMD introduced its next-generation FidelityFX Super Resolution suite named FSR 3. As the third generation of FSR, AMD wants to generate even more pixels in a current frame with interpolated frames, allowing the company to achieve a 2x performance improvement versus the existing FSR 2 technique.

With FSR 3, there's a high probability that there will be at least one sample for every interpolated pixel and no feedback loop since interpolated frame will only be shown once. So any interpolation artifact would only remain for a single frame. AMD has provided a rendering pipeline of a native, FSR 2, and FSR 3 model which can be seen below:

In an early look provided to GDC attendees, AMD revealed that FSR 3 FidelityFX Super Resolution will leverage from:

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!

Latency reduction will also be a key focus area for AMD FSR 3 FidelityFX Super Resolution since the company understands that gamers need both, high frame rates and the lowest latency possible. It also looks like FSR 3 will be very easy to migrate to titles that already utilize FSR 2 integrations and finally, an
