Hello there... I just started trying to speedrun and I'm speedrunning Hollow Knight! I downloaded the auto-splitter and configured it by activating on LiveSplit... But when I get to the splits, the auto-splitter just won't trigger! Is it not seeing what's happening on remote play or what? How do I do this?

You should ask on the Hollow Knight forums.

Didn't know it was separate, sorry...

Autosplitters work on PC games, not console games. Streaming a console game to your computer through remote play is not the same as playing it on PC.
