Question / Help What is replay buffer and how do I use it?

[morpiest]

Hello. I've been having trouble lately with Nvidia Shadowplay and I've decided to move on to a different recording software. I think the best feature of Nvidia's shadowplay was the replay feature. Where if you did something really nice in a game but weren't recording it, you could save the last five minutes. Is that what replay buffer is? If so, how do I configure it
