FidelityFX Super Resolution (FSR) was previously launched by AMD amid a lot of fanfare. For the uninitiated, FSR is a function that improves game performance on PCs and gaming consoles.
FSR soon became the fastest-adopted software product in history, delivering significant performance gains while maintaining a high level of visual fidelity. However, it was not without flaws.
New and Improved
Then there’s FSR 2.0.
Now, AMD has released FSR 2.0, which is a new form of upscaling technique that improves image quality and frame rates in games that support it. This new technology employs cutting-edge temporal upscaling to restore fine geometric and texture detail and increase image quality over FSR’s previous iteration.

FSR is AMD’s response to Nvidia’s Deep Learning Super Sampling (DLSS) technology, which works by decreasing your in-game resolution and then utilizing a spatial upscaling method to enhance the frame rate without putting more strain on the GPU. As a result, performance is improved at a low cost.
FSR 2.0’s Operation
FSR 2.0 uses temporal image reconstruction instead of the original FSR, which worked on the current frame to upscale it to a higher quality image and lacked a robust anti-aliasing solution. To recreate a higher quality image, this technique uses frame color, depth, and motion vectors in the rendering pipeline, as well as data from prior frames. FSR 2.0 also has its own anti-aliasing solution, which replaces the engine’s built-in one.
When compared to FSR 1.0’s straightforward upscaling, this approach has the advantage of being able to reconstruct greater information.

FSR 2.0, while comparable in principle to Nvidia’s DLSS 2.0 and Intel’s XSS, does not feature an AI or ML component, allowing it to function on a larger range of hardware, including Nvidia and Intel GPUs. Although, unlike DLSS, it may not be able to reconstruct as much detail from a low-resolution image.
We only have one example of FSR 2.0 in action right now, thanks to the few samples AMD shared from Deathloop, which was one of the first games to utilize it. At the higher quality present and a lower performance level, FSR 2.0 clearly outperforms FSR 1.0 in this image. FSR 2.0 also resolves greater information than native 4K rendering in some situations.
FSR 2.0 will run on all of the same hardware that FSR 1.0 does. FSR 2.0, like FSR 1.0, can be used on PCs, consoles, and mobile devices, depending on the game developer. In Q2 2022, the feature will be available.
