Valve is working to add support for the Nintendo Switch’s Joy-Con controllers to Steam. As part of it the latest Steam beta, the Joy-Cons will be supported either individually or as a matching pair, similar to how you can use them for either Switch games. If you want to try the feature, you can opt for the Steam beta — Valve has helpful instructions on the Steam website — though fingers crossed that your Joy-Cons don’t experience any displacement.
Valve is also improving its support for the classic Nintendo controllers it sells to Switch Online subscribers, though in the beta patch notes the company didn’t specify exactly how. This feature was introduced to the public version of the Steam client just last week, allowing you to use NES, SNES, N64 and Switch-specific and Sega Genesis controllers on Steam.
And if you want to use a non-Nintendo controller with Steam, you have some options there, too. Valve added support for Sony’s DualSense controller shortly after the PS5 launched in 2020, and expanded Steam support for Xbox controllers in early 2021.
