AMD FSR has the potential to breathe new life into aging graphics cards, and make the balance between game performance and visual quality easier to achieve. But what exactly is FSR, and how does it work?

What Is FSR?

FSR, which stands for FidelityFX Super Resolution, is one of the latest additions to AMD’s FidelityFX image toolkit. It is an upscaling technology, designed to improve the performance of games without loss of image quality and graphical detail.

Playing a game in high resolution such as 4K will often result in a noticeable frame rate drop, even if using a decent graphics card. This is especially true if the game uses demanding effects like Ray Tracing. FSR can reduce the input resolution to as low as 1080p and then upscale the output to appear close to 4K. You get the performance of the lower resolution but with the visual detail of a much higher resolution.

It works by lowering the render quality of a game and then analyzing the image, detecting edges, and reconstructing them at the higher target…
