ok i know what fps means, but how do i find out what my fps is?, i saw some screenshots with it displayed on the HUD
Hit the ~ button on the keyboard (the button in between escape and tab on most keyboards, called a tilde I think.) It's what puts the "nya" in "pinata" or "senor" if that makes any sense.
That button opens up the console, and then from there, you type: cg_drawfps 1 If you want it to go away in the HUD, repeat those steps, but replace the "1" with a zero to toggle it off.
In the same way, but unrelated, I like to turn my gun off, and have nothing but my crosshairs between me and my target. That happens by typing cg_drawgun 0 , I believe.
If you type cvarlist and cmdlist in the console, you can learn a lot of crap to tinker with, but don't get to carried away with changing settings, or a least not before you back up the files.
