4:3 mouse fix

Hello, Rust community, I would like to ask you a question.
How do you fix your mouse on 4:3 resolution so it moves up and down/left and right the
same way it does on the widescreen. X/Y Sens are different in 4:3. For example
in CS:GO there is a command called m_yaw 0.165 when 4:3 and m_yaw 0.22 when 16:9.
