GameChat is one of the big new features of the Nintendo Switch 2. It is a Discord and Twitch-like video chat, multiplayer, and screen-sharing system that uses the Switch 2's new microphone and USB-C camera functionality. With voice chat support for up to 12 people and game screen sharing with video chat for up to four people, GameChat was one of the first features Nintendo highlighted during its big Nintendo Switch 2 Direct last week.

For those who have seen the broadcast, you'll probably note that the overall image quality of the camera and the low frame rate of the streamed game capture isn't broadcast quality or what you'd expect from a premium service. Still, it is impressive to see background removal and how Nintendo is even incorporating this system into Mario Party for mini-games that include the camera for multiplayer.

Although Nintendo or NVIDIA haven't disclosed the full specs of the custom chip powering the Switch 2, we know that Nintendo is leveraging the GPU's Tensor Cores for AI-powered face tracking and background removal, similar to RTX Broadcast.

"Tensor Cores power AI-driven features like Deep Learning Super Sampling (DLSS), boosting resolution for sharper details without sacrificing image quality. Tensor Cores also enable AI-powered face tracking and background removal in video chat use cases, enhancing social gaming and streaming."

We wouldn't be surprised if GameChat was partially built using RTX Broadcast features like background removal, virtual backgrounds, and virtual key lights to keep everybody's faces lit while on camera.

The Auto Frame feature, which automatically tracks movement with cropping and zooming, is probably also being used for GameChat and Mario Party's camera-based online multiplayer features that are exclusive to the Switch 2. Then, there's the AI-powered Noise Removal, which is probably being used because the microphone is on the docked Switch 2 console, not the new JoyCon controllers.
