It has a few interesting features, though. First, it has a screenshot function that connects with Imgur. Steam's F12 function is pretty good for almost any title, but there are some times that you don't want to register the game with Steam, so a second option is welcome. They also have an overlay to control your stream, rather than just an indicator icon.
They added the ability to choose the Twitch Ingest Server, which is the server that the broadcaster connects to and delivers your stream into Twitch's back-end. I haven't used ShadowPlay for a while, but you previously needed to use whatever GeForce Experience chose. If it's not the best connection (ex: across the continent) then you basically had to deal with it. OBS and OBS Studio have these features too of course. I'll be clear: NVIDIA is playing catch-up to open source software in that area.
The last feature to be mentioned might just be the most interesting, though. A while ago, we mentioned that NVIDIA wants to allow online co-op by a GameStream-like service. They now have it, and it's called GameStream Co-op. The viewer can watch, take over your input, or register as a second gamepad. It requires a GeForce GTX 650 (or 660M) or higher.
