The right tool depends on what you are trying to capture
Whether you just want to save an amazing moment that already happened, record an entire session from start to finish, or fine-tune picture quality down to the last setting all point toward a different capture tool. Knowing a few different methods means you can pick whichever one fits the moment.
Instant Replay is a rolling buffer, not a running recording
With NVIDIA Instant Replay turned on, the app is not saving a growing video file the whole time you play β it continuously keeps only the last few minutes in a temporary buffer, and only writes an actual video file to disk once you press the hotkey. That is what makes it possible to capture a highlight after it already happened, without having had the foresight to hit "record" beforehand.
Frequently Asked Questions
Is Instant Replay always recording in the background?
While the feature is on, it continuously keeps a temporary buffer of the last several minutes, and only saves that segment as an actual video file once you press the hotkey.
Does recording with Xbox Game Bar affect game performance?
It uses hardware encoding, so the performance cost is relatively small, but lower-end PCs may notice a slight frame rate dip, so it is worth checking the impact on especially demanding games.
