Here you can find the config files I use for Counter-Strike: Global Offensive. Feel free to explore them and use them.
First, locate where your game folder is. Usually C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive in Windows and something similar in other OSs. The .cfg files (autoexec and prac) and the video settings (video.txt) should be saved in csgo\cfg. The radiopanel file should be saved in csgo\resource\ui. The csgo_bananagaming file should be saved in csgo\resource. The launch options file shouldn't be saved anywhere (see below). Read below to find out what each file is doing. You probably don't want every one of them.
This config is executed every time the game is loaded. Here you can find my aliases, binds, configuration options and other cool stuff.
I use this config when I practice flashes/smokes on a private server. It sets some variables such as sv_cheats 1 to make the practicing easier. I usually start the config it with F11 and give nades with F12 (see autoexec), but it can be started with exec prac from console.
Did you know there are some hidden radio commands in the game that you can use? Replace this file and they will appear in the radio menus. See more info here.
These are the launch options I use to start the game. Here you can see how to add them. Be careful!!! The -threads and -freq options should be individual to everyone, otherwise you can harm your hardware. You have been warned.
