Some graphics cards have hotkey for you to turn your fps on, although that doesn’t show you the server fps. Sadly the toggledebug hud was stated that it was an admin feature and that we weren’t ever suppose to be able to access it. I believe it was removed because people were using the toggledebug hud 2 feature to see building pieces which allowed to easily scout for bases in pvp. Sadly as it also was used to help find sky and undermesh bases.
