Steam Deck users will be able to enjoy a solid performance boost on their games when the handheld gaming PC arrives, as it'll have integrated support for AMD's FidelityFX Super Resolution upscaling tech out of the box. That technology will work in tandem with SteamOS, although if you mod the console to use Windows, you'll risk losing access to it as FSR is connected directly to the default operating system.

"FSR is already available for some applications that support it. Games that already include FSR will work as is, but also FSR support will be included as part of an OS future release. Once that happens, games could potentially make use of FSR even if the games themselves don't natively support it," the Steam Deck FAQ added.

If you're unfamiliar with the FSR software, it's a technique that renders frames at a lower resolution and then uses an open-source spatial upscaling algorithm to make the game look as if its running on a higher resolution setting. It's similar to Nvidia's DLSS technology and uses linear upscaling as opposed to AI-powered rendering of its competition, but the key difference here is that while DLSS is exclusive to RTX-equipped graphics cards, FSR can in theory work on any GPU.
