The Elgato Game Capture HD60 S is not the HD60's successor; it's more like a little brother with its own special streaming feature. It can also record, even in 1080p60, but it's been specifically developed as a streaming device. Unlike the HD60, the Game Capture HD60 S has barely any lag at all when broadcasting your gameplay live. This is thanks to the USB 3.0 connector that's absent in its brother, the Live Streaming feature that allows you to broadcast directly on Twitch and YouTube, and the Stream Command feature, which lets you add a webcam part, overlays, and all kinds of other things.
Note! This game capture works best on a PC with NVIDIA video cards.
