The latest Steam client beta has added official support for Nintendo Joy-Con controllers, making it far easier to use Switch-style controls with your PC games.
On August 4, a Steam client beta update (opens in new tab) went live with two changes, the more prominent of which is this: "Added support for Nintendo Joy-Con controllers, both individually as a mini-gamepad and combined into pairs." The update also notes that Nintendo Online classic controllers now have "improved support." It typically takes anywhere from a few weeks to a month for a beta update to go live on the main Steam client, so you can expect the feature to be available for everyone fairly soon.
On July 27, Steam added official support (opens in new tab) for the Nintendo Online classic controllers - the modern bluetooth controllers made in the shapes of NES, SNES, Genesis/Mega Drive, and N64 gamepads which Nintendo sells directly through its own store.
Yes, now, with official support for both N64 controllers and Joy-Cons, Steam finally supports all of Nintendo's worst controllers.Read more on gamesradar.com
