AMD FSR 3 Might Generate Up To 4 Interpolated Frames & Be Enabled On Driver-Side

Some new details of AMD's FSR 3 "FiedilityFX Super Resolution 3" technology have been revealed in the latest listing over at GitHub. The new details seem to point out that the upcoming tech might be enabled on the driver side and will generate more than 1 interpolated frame.

AMD FSR 3 Coming Soon! New Details Reveal Up To 4 Interpolated Frame Generation & Driver-Side Implementation

The information was revealed within the latest GPUOpen code available at GitHub and spotted by @Kepler_L2. The two most interesting lines of codes within the listing suggest that AMD is indeed going to implement a form of frame generation tech which should be expected in FSR 3 "Fiedility FX Super Resolution" since that was talked about the last time.

Some interesting implications for this:

- FSR3 being driver-side would not work on NVIDIA GPUs
- "FrameGenRatio" implies it can create more than 1 interpolated frame per real frame. https://t.co/WGEXcQlUH6

The code states that AMD's FSR 3 will have a Frame Generation Ratio of up to 4 interpolated frames which means for each real frame, the technology can generate up to 4 interpolated frames. NVIDIA DLSS 3 also has frame generation technology which will generate one interpolated frame for every single frame when enabled. However, NVIDIA's DLSS 3 doesn't allow users to modify the frame gen value to anything beyond 1 nor it's part of the suite yet. DLSS 3 makes use of the tensor hardware & learning models to generate the interpolated frames and even with all of that AI assistance, the company still had some issues related to ghosting and screen tearing in the early implementations which are now being sorted out.

AMD has so far said that they aren't entirely going to use AI for FSR "FiedilityFX Super Resolution" since they have more suitable use cases for the AI hardware. If FSR 3 does allow users or devs to modify the frame generation beyond 1 interpolated frame, then it would be interesting to see if the resultant image quality is good enough and pleasing to gamers or if it turns out to be a very broken mess in its first few months too.

Besides this, it is also reported that AMD FSR 3 "FiedlityFX Super Resolution 3" might be integrated on the driver side. This would mean that the technology won't be hardware-agnostic like FSR 1 and FSR 2 and not run on Intel/NVIDIA hardware. However, the company has placed bets on the open nature of its FSR software so that might not be the case. AMD has yet to officially release FSR 3 and since GDC 2023, we haven't heard anything new but we can expect the technology in action soon as more mainstream RDNA 3 graphics cards hit the market.
