AMD FidelityFX FSR Source Code released & updates posted

To begin with, the company released the source code of the technology to the public under its GPUOpen initiative, under the MIT license. This makes it tremendously easy (and affordable) for game developers to implement the tech. Inspecting the source, we find that FSR relies heavily on a multi-pass Lanczos algorithm for image upscaling. Next up, we learn that close to two dozen games are already in the process of receiving FSR support. Lastly, it's announced that Unity and Unreal Engine support FSR. With the source code now fully available, nothing stops developers from adding FSR into their games. Unlike nVidia's DLSS solution, FSR requires almost no engine tweaks, you just add the shader pass into your rendering pipeline. In a separate PDF document AMD went into more detail on how to integrate FSR, what inputs are required, and how to present the new rendering options to the end-user.

We took a closer look at the source code AMD is providing, and it's really the full source. There are no external dependencies or DLLs. You are free to modify and adapt as you see fit. This makes FSR an interesting tech for modders, who should be able to more easily integrate the tech into existing games, through hooks. Also there's nothing that would prevent this from running Linux. AMD's sample code includes Windows samples only at this time, but integrating FSR with other operating systems, even cell phones is trivial at this point. AMD has also released a demo for FSR, which lets you dig into all the settings options and compare them in a way that's better suited to investigation, than a hectic game.
