Thank you!

Hello, I was confused about something and need clarification please.
in Guides, FAR confg Guide, it says "As of November 2021, FAR (Fix Automata Resolution) will be required for all leaderboard submissions due to a framerate glitch found in both Steam releases of the game" and in Game Rules it's mentioned there are 3 methods to show fps counter one of them is FAR.

My question is can I use Steam fps counter or Nvidia GForce Experience fps counter? or FAR is a must? Because in Game Rules it says FAR isn't the only method that's required but in Guides it says FAR is required.

I apologize for the long question just got confused, thank you for your help.
