The Elder Scrolls 5: Skyrim is now the first third-party game to allow video capture on the Nintendo Switch.

A patch for the game, referred to as Update 1.1, added the new functionality on Nov. 16. Now players can use the Switch’s Capture button to record in-game clips. Bethesda issued no formal statement, but did mention the feature on its development blog.
