In the battle for the best super-sampling solution between AMD and NVIDIA, the former is not disarmed by the rise of the latter.

Most video game enthusiasts, especially if they play on a PC and have an NVIDIA graphics card, are familiar with " deep learning super sampling " or "super sampling assisted by artificial intelligence", more commonly referred to as DLSS. This technique uses artificial intelligence to calculate the image of a game that is actually displayed on the screen in a higher definition than the graphics card has rendered. The goal is to get the best of both worlds: the beauty of a higher definition image and the display speed of an image that is easier to calculate.

Over time, DLSS has become more efficient and popular with development studios and gamers alike. A success that could not leave AMD indifferent. So NVIDIA's big competitor launched its own technique, which relies less on artificial intelligence calculations, but still offers a rather similar objective. FidelityFX Super Resolution (or FSR) is not yet at the quality or adoption level of DLSS, but it is making significant progress since its debut in June 2021 with FSR 1.0. Last November, when announcing its new Radeon RX 7900 XT and RX 7900 XTX graphics cards, AMD actually promoted FSR 3.0, which is scheduled for release sometime in 2023. Until it is available, the American company logically emphasizes the intermediate version, the FSR 2.0.

More open, less fan of the proprietary format than NVIDIA, AMD has just announced the free availability of FidelityFX Super Resolution 2.2 on GPUOpen. The idea is obviously to give all the keys to the developers who can now access the open-source API and its source code so that, in a second time, they can integrate the FSR on their next productions. Beyond the technique implemented, it is indeed the number of games that support the most efficient technologies in the world that will make the difference.

At this level, AMD is aware of the delay it has accumulated on NVIDIA and even if the open-source gene is more in AMD's DNA than in NVIDIA's, we understand the interest of the Radeon developer in this gesture. At the moment, AMD can indeed boast of having a catalog of 250 FSR games. Problem is, these are games for which FSR is "available or in the process of integration" and that AMD blithely mixes support for FSR 1.0 and FSR 2.0. They are growing fast, but at the moment it's more like 65 games that are actually FSR 2.0 compatible.
