One of the most anticipated announcements at Computex 2021 was that of AMD and its GPU news. The company introduced the technology FSR (FidelityFX Super Resolution). With it, it intends to compete with NVIDIA DLSS, but the positive thing about AMD's is that it is open source, so the community can intervene in its development, improvements and portability.
AMD has been betting on open source projects for some time, since it knows that it is a guarantee. Without going any further, thanks to the fact that this company opened the Mantle API code, we currently have the mighty Vulkan. Otherwise, you would still be relying solely on OpenGL.
AMD has proudly displayed FidelityFX Super Resolution to improve the performance of its future Radeon graphics cards. And, because it is an open source project, compatibility will not be a major problem, since the community will take care of taking it where it is required.
In addition, the positive is that AMD FidelityFX Super Resolution will also be able to work on the nvidia graphics cards, so it does not exclude these. It just depends on the green company to optimize their hardware for FSR (something that almost certainly won't happen). They are committed to DLSS (Deep Learning Super Sampling), a different technology than FSR, but the result is the same, that is, obtaining higher resolution without penalizing speed (FPS).
In addition, in the case of NVIDIA, as is usual in this firm, it is a proprietary code. The graphics company has full control of it, and works together with partners to implement it in video games. Something not very positive for Linux gaming and for the adaptation of this other technology, since the opening of this type of project brings new hope.
