Well the bot is running its code in the game without having the client opened aka clientless. The game Silkroad Online has a bot I used that is called "Sbot" and it utilizes this in their bot which allows me to go clientless which shuts down the client but keeps it running in the background as I don't need any visuals to have the bot do its work. I am not a coder but I know its making the usage slim to none as there is just code being executed without the game client being opened.
I have tried to lower and is working so far good and will keep an eye out if you guys make clientless option. Check "Sbot" for the reference of clientless.
