Yuzu also offers a resolution rescaling feature that simulates docked, undocked and beyond-native resolutions. The implementation will eventually be replaced with one that allows the use of local BCAT files dumped from a Nintendo Switch. This feature was later removed due to being non-functional. It also added AMD FidelityFX™ Super-Resolution as a window adaptation filter among others.Yuzu used a network service called Boxcat as a replacement for Nintendo's BCAT dynamic content network. In October of 2021, resolution scaling was added to the emulator that allowed it to render games up to 6x the original resolution or 0.5x on the low end. In July of 2021, yuzu's shader decompiler was rewritten, allowing the generation of pipeline cache for Vulkan users and providing a considerable performance boost. This feature appears to cause audio slow down, so the developers recommend enabling audio stretching in order to mitigate it.

In May of 2020, multicore CPU emulation was implemented, improving framerates on many titles. The team covered all the changes that month in another progress report from September 2018. This long-awaited exclusive brought a lot of interest in the project. Yuzu started showing some 3D rendering on Super Mario Odyssey in early August 2018. The post also covers a surprising number of similarities between the hardware and firmware of the 3DS and Switch, and why portions of Citra were reused in yuzu. This progress report from July 2018 details the extensive work required to research the Switch and get yuzu up and running, chronicling the compatibility status of a small bundle of games and apps over time. Three months later, yuzu was able to run its first 3D rendered game, Minecraft: Story Mode. In late April 2018, yuzu booted its first Switch exclusive, 1-2-Switch.

The Binding of Isaac: Afterbirth+, Puyo Puyo Tetris, and Cave Story+ were the first games to boot. Yuzu reached in-game on several Nintendo Switch exclusives in November 2019, and has been improving in compatibility by the day with active developers ever since. As of March 2022, an estimated half of the Nintendo Switch library can be played from start to finish, like Super Mario Odyssey, which had correct graphics and speed after 1 year of it getting to boot up.
