FidelityFX Super Resolution 3 (FSR3) Will Be Open Source According To AMD

The AMD software engineering team is revealing the initial details about their next upscaling technology at the 2023 Game Developers Conference (GDC). During the AMD GDC briefing on FSR3, not all the details were revealed. Since the technology is still in active development, there is currently no official release date. Despite this, FSR3, which is the successor to FSR2 and a highly anticipated competitor to DLSS3, may be the most significant technology that AMD will release this year.

Despite the announcement made almost four months ago, it seems that AMD still needs time before they can ship their frame interpolation technology, similar to NVIDIA’s DLSS3. However, AMD may have an advantage in supporting more than one GPU architecture, as indicated by Azor Frank in November of last year. Despite this, there was no further mention of this during the GDC update.

Rather than discussing multiple GPU architecture support, the AMD software team has revealed that they are aiming for a 2x performance increase compared to FSR 2.0. This boost would be achieved through generating a higher number of pixels via interpolated frames. This information is valuable for both gamers and game developers.

According to AMD, FSR 3.0 will provide a smoother gaming experience compared to FSR 2.0, as the company is focusing on reducing latency to achieve the best possible gameplay. Additionally, AMD aims to make the transition from FSR2 to FSR3 as easy as possible, which could lead to faster adoption of the third-generation technology.

The most significant announcement from AMD is that FSR 3 will be open source through the MIT license. This means that the technology will be freely available and editable by anyone. Once FSR3 is ready, the company is expected to release samples and full documentation, which may result in FSR3 mods being developed for NVIDIA DLSS3 games, as was the case with DLSS2/FSR2.
