Question: how to apply cfg in cs go?
Answer: Go to your Steam folder (this is usually in 'Local Disk (C:)') and then navigate to 'Program Files (x86)' -> 'Steam' -> 'userdata' -> YOURSTEAMID (this is a bunch of numbers that corresponds with your personal Steam ID number) -> '730' -> 'local' -> 'cfg'. Place your old config. cfg file in your backup folder.
