New Super Mario Bros. U Deluxe is a spruced up version of the 2012 Wii U launch title. This is the complete package containing both New Super Mario Bros. U and its add-on New Super Luigi U. According to Digital Foundry's latest video upload, about the only thing missing is Miiverse integration. Apart from this, the conversion - in terms of scope - is similar to the likes of Mario Kart 8 Deluxe.

So, how does the Switch version look and perform in contrast to the original effort? Crucially, nothing has been downgraded. The resolution has been bumped from 720p in the Wii U release to 1080p docked on Switch. There are many subtle refinements throughout, although the texturing and assets are broadly identical. Out of all the characters, the only one to receive a visual makeover is apparently Peach, with each of her features now more defined. Other than this, there are also high-resolution shadows on display.

In the portable mode, the experience is mostly the same - with the core visuals identical to the docked mode, barring a change to a native 720p. In contrast, Wii U portable play ran at what was "essentially" 480p. In terms of the performance across both modes of play, the Switch iteration appears to have no issues maintaining 60fps at all times.

Digital Foundry admits this is not the most ambitious conversion and explains how most of all, it highlights the conservative nature of the original game. In saying this, Nintendo could only improve upon it in so many ways, when working with such simple visuals.
