The Legend of Zelda: Breath of the Wild is a multiplatform release that is also being released for the Nintendo Wii U in addition to Nintendo Switch.
The advantage of Zelda: Breath of the Wild on the Nintendo Switch is additional portability for the game, while on the Nintendo Switch, the user is restricted by the wireless range for playing the game on the Wii U gamepad. There is also difference in the image quality with the Wii U version operating at 720p compared to the 900p resolution of Nintendo Switch.
Digital Foundry has now compared the final retail version of Zelda: Breath of the Wild for the Nintendo Switch and Wii U. They also have compared the frame rate between both versions of the game and interestingly enough, neither version of the game appear to offer smooth 30 fps here.
The video above gives us a detailed analysis of both version and confirms that the visual difference, especially in term of effects, is negligible between both versions. The main difference that does exist is minimal and mostly hard to see in motion unless we compare them side by side. The effects are identical for the most part aside from texture filtering being a notch higher on the Switch.
The Legend of Zelda: Breath of the Wild is available now for the Nintendo Switch and Nintendo Wii U.
