The folks at eurogamer's Digital Foundry have further digged into the technical aspect of Zelda BOTW and revealed a new piece of discovery. It was previously stated that Zelda renders in 900p when docked and 720p when undocked. While those resolutions are true, it has issues maintaining 30fps at all times however. That's why it uses a technique that's called Dynamic Resolution Scaling. This technique decreases the resolution in processor intensive scenes from 1600x900 to 1440x810 (docked) and from 1280x720 to 1152x648 (undocked) in order to maintain 30fps. It appears this isn't exclusive to the Nintendo Switch game, because the Wii U game uses the same DRS.
