The Delay Server is a feature of XSplit that allows you to put some delay on your stream. This can be a useful feature for streamers with restricted real-time permissions, or for gamers who wish to delay competition content. Here's what it looks like:
To start it, simply open XSplit Broadcaster, and click on Tools >> Activate Delay Server. You can specify the delay in seconds. Please take note that this feature is only available for Premium users.
Once you are done simply just leave the Window open, and start streaming!
