-prediction makes the other person seem laggy so you can aim at them better.
-forgot what aim key is
-window mode makes your ca in a window like your firefox or whatever
-cam position is like ghostmode but you cant control it your just above where your character is or below (dont know how to explain)
-unlock cursor is when your in window mode and your mouse cursor moves out of the screen and on to your desktop and mess up your game so when you lock cursor its like your mouse cursor stays in one spot so it wont move out of ca
sorry for the explaination if it is bad
