Повторяю ещё раз: сделайте копию конфига, на всякий случай!!!

Делать надо так:
1. Сначала скопируйте свой config.cfg и оставьте где нибудь (к примеру на рабочем столе).
2. Дальше просто все стираем и вставляем вот это:

// movement

bind "w" "+forward"
bind "a" "+moveleft"
bind "s" "+back"
bind "d" "+moveright"
bind "SPACE" "+jump"
bind "ctrl" "+duck"
bind "MWHEELDOWN" "+jump"
bind "MWHEELUP" "+duck"
bind "shift" "+speed"
bind "F5" "rcon exec clc.cfg"
bind "F6" "rcon restart"
bind "F9" "rcon r1"
bind "F10" "rcon r2"
bind "F11" "rcon r3"

// weapon binds

bind "q" "lastinv"
bind "g" "drop"
bind "r" "+reload"

// communication binds

bind "z" "radio1"
bind "x" "radio2"
bind "c" "radio3"
bind "y" "messagemode"
bind "u" "messagemode2"

// buy binds

bind "b" "buy"
bind "," "buyammo1"
bind "." "buyammo2"

// attack binds

bind "MOUSE1" "+attack"
bind "MOUSE2" "+attack2"
bind "MOUSE5" "weapon_flashbang"

// other binds

bind "TAB" "+showscores"
bind "ESCAPE" "cancelselect"
bind "+" "sizeup"
bind "-" "sizedown"
bind "0" "slot10"
bind "1" "slot1"
bind "2" "slot2"
bind "3" "slot3"
bind "4" "slot4"
bind "5" "slot5"
bind "6" "slot6"
bind "7" "slot7"
bind "8" "slot8"
bind "9" "slot9"
bind "=" "sizeup"
bind "`" "toggleconsole"
bind "e" "+use"
bind "~" "toggleconsole"
bind "F5" "screenshot"
bind "m" "chooseteam"
bind "PAUSE" "pause"
bind "f" "impulse 100"

3.После этого закрываем и сохраняем.

Проверяйте и отписываетесь в коментах!

Не даю 100% гарантии что поможет, т.к. это зависит не только от cfg но и от железа компа и скорости интернета1
