Lego City Undercover runs at a higher resolution on Nintendo Switch than Xbox One

Lego City Undercover is one of the first games to be on the Nintendo Switch at the same time as Xbox One and PlayStation 4 as the console just launched in March. It turns out that the game runs at a higher resolution on the Switch rather than the Xbox One and that is when it is docked since the handheld part of the console is 720p.
Here is how each console runs the game:
S4 version : native 1080p at all times, locked 30fps while outside but caps at 60fps when you’re indoor (note : the original Wii U version never got higher than 30fps)
Switch version : native 1080p at all times, but locked 30fps no matter if you’re indoor or outside. It has some noticeable dips when you’re playing in portable mode, but DF couldn’t provide footage.
Xbox One version : running at sub-native horizontal pixel count (1300 to 1400x1080p), and has the same framerate difference as the PS4 one.
Here is what Digital Foundry says:

“Lego City Undercover’s 2017 revamp also gives us some indication of how far the engine technology has moved on in the last four years. The lighting system is completely revamped, with a move to physically-based rendering. The effect on the game is transformative in this respect, and the inclusion of more refined ambient occlusion adds subtle depths to the nooks and crannies too. The effects pipeline, the quality of the shaders, the detail in the core art assets and normal maps – everything gets a substantial upgrade. With Lego City Undercover essentially re-architected for a more modern engine, there are other enhancements too: moving out of the centre of Lego City, more of an attempt has been made to show far-off detail in the game areas.”

Here is what they think overall on the Switch:

“The good news for Switch owners is that most of the upgrades bestowed by the more modern engine are all present and correct in their version of the game. Looking at the comparison footage, it’s remarkable to see how well it holds up in motion next to the PS4 and Xbox One versions, with only strategic nips and tucks here and there.”
