Found it! I knew I remembered seeing this before, but couldn't remember how when you asked because I seldom utilize this feature; so I fiddled around with my last game and tried to figure out how to get it to play in real-time.

In the link, they show a picture of the button I remembered seeing, but don't see now. I found it eventually, but it is kind of "sneaky" lol.
First, you have to have the pgn set up WITH timestamps and the "real-time" button only appears AFTER you click "play/pause." I spent a while looking for it, but it only appears after you click this. Hope my explanation makes sense and you can find it now
Hello
Sometimes I would like to check my games in real-time, when I play click it's just automatically second after second. Is there a way to see how it exactly was?
Thanks for your help
