As of 10/27/2020, all PC submissions are required to have an FPS counter shown. The video below shows how to turn on the FPS counter.

It's recommended to have "high contrast colour" checked off in order to make the FPS counter more visible.

To make the FPS counter to appear in recordings, you'll need to check off "Capture third-party overlays" in the game capture's properties in OBS.

Note: Make sure your LiveSplit window does not cover up the FPS counter.
