So there's been some demonstration of the Xbox app that will be coming with Windows 10, and depending on your gaming needs you either know you'll be making use of it (Lone) or couldn't care less (Digm). Or possibly you just don't know (me).
One of the functions it will come with though will be useful to small content creators who wish to grab footage of their games. The Game DVR that is included with the app will allow for the use of Windows to capture said footage, eliminating the need for a third-party program to do that very task.
The app will capture either the most recent 30 seconds or can be set to start and stop manually. There's a few options for length and audio/visual quality and having it built-in seems like a very good thing. The only question mark over it as far as I'm concerned is how much of a performance hog it'll turn out to be. Maybe also ones over how good the quality capture can be set (and whether it does capture at that quality) and the format of the video/audio output. Also, can you separate game audio from microphone audio?
... Okay, so maybe there's more than one question mark over it.
Either way, sounds like Microsoft are observing what gamers want, so that's good. Hope it works decently.
