most enthusiasts invest in a dedicated head tracker myself inc for superior look around ability

good luck in setting up your mini stick to do that i suggest you bind your keyboard arrow keys to up down left right see what its gonna be like as a test
or just swap your bind file after backing up your one to a safe place with the one provided earlier where look around is on the joystick mini stick
which you can swap back after trying this out
i assume you have read and understood the bindings guide sticky at the top of this subforum
