This Game DVR feature may or may not be enabled by default, depending on your PC’s hardware. If you don’t care about recording your gameplay, you’ll want to disable this feature. On a slower computer–or if you just want maximum graphical horsepower for your games–it can noticeably slow your in-game performance and lower your FPS. Unfortunately, Game DVR takes system resources.
If you don’t choose to save it, Game DVR discards that video and continues recording in the background. This allows you to play games normally and then decide to save the last five minutes of gameplay to a file when something cool happens. Game DVR can automatically record video of your PC gameplay in the background with “background recording”, saving this video to a file when you choose. The Game DVR feature in Windows 10 was originally part of the Xbox app, and it’s modeled on the similar feature on the Xbox One.
