At the Game Developers Conference (GDC) 2023, the AMD software engineering team has revealed details on the highly-anticipated successor to FSR2, FidelityFX Super Resolution 3.0 (FSR3). 

While still in early development, FSR3 promises to offer an upgrade path from FSR2 and compete with NVIDIA's DLSS3 graphics as an enhancer/upscale. The technology relies on frame interpolation. The engineering team is aiming for a 2x frame performance improvement compared to FSR2, resulting in a smoother overall gaming experience and allowing developers to focus more GPU time on visual quality. However, there are potential setbacks, such as difficulties in producing non-linear motion interpolation on 2D screen space motion vectors and the need to interpolate all post-processing, including the user interface in the foreground. Despite this, FSR3 is expected to reduce latency and make the upgrade path from FSR2 as easy as possible.

One major announcement is that FSR3 will be open-source through the MIT license, making it free and easily editable for anyone. AMD's focus on reducing latency and improving the gaming experience with FSR3 could significantly impact how quickly the third-generation FidelityFX Super Resolution is adopted.
