A few weeks ago, we posted the news that a private build of Yuzu, the Nintendo Switch emulator for PC, allowed upscaling of games beyond their native resolution.

　　Now, the development team has finally released this new feature, dubbed 'Resolution Rescaler', to all Patreon backers. They have also explained how it works while adding that it's still very much a work-in-progress.

　　As you might expect from the name, this feature increases native resolution through a set of rules enforced by a profile, very similar to other emulators such as Cemu. You can select Profile Scanner (Native) option in the Internal Resolution drop-down list.

　　When this option is selected, yuzu will continuously learn more about your specific games rendering methods, and will help create a resolution profile for that game.Once a profile is generated or obtained, the user can then select what multiplier they would like to increase their resolution by (2x, 4x, etc).You can find these rescaling profiles under %APPDATA%/yuzu/rescaling/ on Windows and ~/.local/share/yuzu-emu/rescaling/ on Linux, or you can right-click the game on the UI and click on Open Rescaling Profile.This of course doesn’t come without a few kinks that need to be ironed out. For now, some of the dev teams known issues include:

　　Super Mario Odyssey and The Legend of Zelda: Breath of the Wild won’t rescale correctly on the edges due to a hardcoded AA shader that those games have.

　　The game itself will still look better and more accurate, but you’ll noticed the jagged edges typically associated with hardcoded AA games.Pokémon: Let's Go and some other games have small rendering artefacts when rescaled, such as the flames on Charizard’s tail do not render.That’s not all that has changed, other notable fixes in the latest Yuzu release include:

　　sRGB has been fixed. This essentially corrects some games that looked lighter than usual.Viewport and scissor testing have been corrected, which fixes a ton of issues in many different games, most notably in Hyrule Warriors.Tons of refactoring changes, to better prepare us for our Vulkan backend and other future improvements.Reworked GPU buffer cache is now more accurate and faster, which lead to fixes in Super Smash Bros. Ultimate, Onimusa Warriors, and many other titles.Corrected our shader code to help set up preparation for Fire Emblem: Three Houses.Several fixes for Xenoblade 2 - character models look better and most vertex explosions are gone.YouTuber BSoD Gaming has published a new comparison video, showcasing the difference between running Super Mario Odyssey at 1080p and 2160p with Yuzu.
