Most games have built in commands in the console to show fps, but the easiest way is to download fraps. http://www.fraps.com/
I know the the code to check your FPS in CoD2 Single Player is "cg_drawfps 1" (without the quotes) but that code doesn't work in the multiplayer. I don't know if this is relevant for you,but I also know that the one for Steam games (HL2, CS:S, DoD:S, etc.) is "cl_showfps 1" (without the quotes).
Brother you can use ATT from this site. Or a small app called fraps. Once you have these and don't know how to oc then ask that question @ that time.
Fraps will show you the FPS on any DX game and a whole lot more. http://www.fraps.com/ http://www.majorgeeks.com/download.php?det=3934 Fraps is a utility for DirectX and OpenGL games. It can best be described as: Benchmarking software - see framerates on screen and log them to file. Calculate the average framerate between any two points. Screen capture software - take screenshots at the press of a button with files automatically named and timestamped. movie maker software - realtime recording of your gameplay to high quality AVI video files. - Requires Direct X 9.0b - Requires Windows 2000, Windows XP, or Windows 2003 - Requires Pentium 3, Pentium 4, Athlon, or Duron processor - Works best with an Nvidia Geforce 2/3/4/FX, or an ATI Radeon 9xxx graphics card. - Must be installed under an Administrator account.

I did so, but now do not want to see this FPS anymore also i forgot where i made them visible :O - can you tell me that position ? Thanks...
For Source games, net_graph 3 is generally more useful and is also required by many leagues But yeah, you did hit the nail on the head. Ingame commands are usually better than separate programs. I personally dislike Fraps.
