Anyupdates for MCC regarding multiple inputs

I really want to enjoy these games and use my steam controller as intended. When I try to use joystick movement with mouse aim the entire game becomes unresponsive for seconds at a time. Has the developers with their extra time due to the delay for the next halo game put out any new quality of life updates for PC?

Another question, is it possible to disable the controller aimbot so it doesn’t cause the game to become unresponsive when using joystick movement with mouse aim?
