how do you enable frames per second meter

Linux + Windows: On Steam, click "Steam" in the top-left, "In Game" tab, turn on "Enable the Steam Overlay while in-game" if it's off, scroll down to "OVERLAY PERFORMANCE MONITOR" and set it to show top-right or top-left.

Linux alternative: You can enable mangohud as a launch option (mangohud %command%), though some recording setups don't pick up mangohud. Consult your distro's wiki.

Nintendo Switch: I have absolutely no idea.
