The Nintendo Switch on PC was emulated faster than previous Nintendo platforms like the Wii U and 3DS, with the introduction of the Yuzu emulator (created by the same team as Citra, the Nintendo 3DS emulator) less than a year after the console's release. This is mainly thanks to the NVIDIA Tegra platform, whose architecture is well known to programmers and which is quite easy to emulate. Since then, Yuzu has been able to run games such as , , PokΓ©mon Let's Go and others.
However, Cemu, the Nintendo Wii U emulator, retained one significant advantage over Yuzu - the ability to run Wii U games at much higher resolutions (4K and higher) for improved image quality. But Yuzu will soon have an AI-powered resolution scaling tool.
This new tool multiplies the width and height of the Render target textures based on the profile. This means that if the original Render target was 1920 Γ 1080 pixels, then doubled on each side it would be 3840 Γ 2160 pixels. This improves the clarity of the final image. This is how other emulators work (Dolphin, Citra, Cemu and others). Yuzu's main difference is that a profile is needed because not all Render targets can be scaled (for example, some are used to render cubemaps). Yuzu will include an AI-based resolution scanner that will determine which Render targets can and cannot be changed based on a set of rules.
The BSoD Gaming YouTube channel has already tested this new feature through a collaboration with Yuzu developers. The videos below show attempts to run Super Mario Odyssey and other games at 8K on a PC (i7-8700k @4,9GHz, 16GB DDR4 @3200MHz, overclocked GeForce GTX 1080 Ti 11GB, 256GB NVME M. 2 SSDs). When the innovation will be available to Yuzu subscribers on Patreon is not specified, but the future of Nintendo Switch emulation on PC looks promising.
