NVIDIA GeForce "Playback the last 3 mins" Feature

Hi,

Anyone here who uses this and can tell me how it works?

I hit Alt + Z, and the item comes up where I can look at and set criteria. It tells me where to record, where to host television shows (I guess those are called live streams?).

But it doesn't in so many words tell me how to access the part where it will automatically save the last rolling 3 minutes of game play if I want to replay it, without having hit the record button ahead of time.

Does anyone know how to do this? Is there any advantage to doing this, versus pressing Alt + R in the regular game?

I hope I'm making sense here. Thank you in advance.

 

Nadeox, Thank you so much. You cleared up a major misconception I had. That is to say, I thought it was "the last x minutes" of a 3D replay where I could place the camera at any angle to review that action. I was not aware that it was only a video playback of whatever viewpoint I had happened to have it set at-- during those x minutes.

Now I understand. That's cool that there's a way to playback what I didn't think to manually record in the first place. But it's not nearly as useful as a manual implementation of Alt + R.
