Something for the console (F10) that works online:
stat fps - Frames per Second are displayed (no need for fraps runing in the background^^)
behindview 1 - switch between 1st and 3rd-person-view. As spectator you can see where people aim at... if you think someone is a aimbotter, this can help to get sure.
Hey Vegas you can write Behindview only too.
I know another one allweapons for all weapons (inc. Translocator :D)
allammo for all ammo
(this orders only works offline)
