when you hit tab it opens up a console... what do each of the commands do and what do i type to use them?

typing "fps 1' will enable the fps counter, typing "fps 0" will disable it

typing "speed 1' will enable speed counter, typing "speed 0" will disable it.

I recommend using the settings tab to set fov and sens since it's easier.

and you dont need a fps limit, so don't use the command

cool beans
