Cs:s

I got 2 quick questions.
1.) How do I install maps that I have downloaded into CS:S
2.) How do I see the FPS of the game?

P.S: I"m talking about Counter-strike:Source for those of you who are unsure.

Thanks in advance.

you download maps automatically from servers so you shouldn't need to install anything but if you want to the directory is
C:\Program Files\Valve\Steam\steamapps\(your user name)\counter-strike source\cstrike\maps

open console using the ` key and type in net_graph 3 hit enter and it should come up in the corner for fps

or just type in "show_fps 1" (w/o the quotes) which will show in the top right corner....net_graph 3 shows all the other stuff like pings and chokes and sometimes gets in the way of the HUD
