Yuzu Switch emulator gets AMD Fidelity FX Super Resolution (FSR) support for better performance when running BOTW and Super Mario Odyssey at 4K and beyond

The Yuzu Nintendo Switch emulator recently received a major overhaul to its resolution scaling feature. Alongside a significantly more effective approach to resolution scaling, Yuzu also now features AMD's FidelityFX Super Resolution upscaling solution. FSR is being leveraged here to offer significantly better performance when upscaling Nintendo Switch games to 4K and beyond, without compromising too much on image quality. 

Surprisingly, the initial screenshots shared by the Yuzu dev team indicate that FSR scaling seems to deliver better image quality than the old resolution upscaler with bilinear filtering enabled. In the screenshots, we see FSR better reproduce high frequency detail in the Metroid Dread comparison, despite running at a lower nominal resolution.

When AMD introduced FidelityFX Super Resolution, it was touted as an open source alternative to black-box scaling techniques like NVIDIA DLSS. While DLSS certainly delivers better image quality, especially in DLSS 2.0 titles, FSR's open source nature makes it possible for projects like Yuzu to just plug it in and deliver a "good enough" upscaling alternative.
