Are you not bored typing fps SHOW START every time?
I realised we have many new members who are not able to sing the two pages of conf.ini by heart (shame!) so you may find this of use:
In the same directory as the conf.ini (the famous MyDocuments/ etc etc...)
Find the file RCU
Open it with the text editor
at the bottom add following lines of text:
@a aa fps SHOW START
@a ab fps HIDE STOP
aa
save and close
From now on, if during the game you decide to start the fps display, press Alt-TAB, type
aa press enter, exit with Alt-TAB. The fps measurement will appear on your screen.
To remove it, repeat the procedure typing
ab
The last line
aa in the RCU file spares you from all the work, with it every time you start the game you have thefps measurement displayed automaticaly (you can remove it of course if you do not want this).
Since I have this strange feeling that we will spend the next months talking fps, it may prove a little handy
Happy Flying (ehem, Testing...)
