I always turn that off. Being used to a mouse I always turned my right stick sensitivity WAAYY up so I could aim quickly, but the aim assist would always throw off my muscle memory for how far/long to pull the stick. Then I tried gyro/touchpad aiming for shooters and couldn’t get the hang of it, I like playing with the deck resting on something, I can’t just hold it in the air the whole time I’m playing. Now I just play shooters on PC and everything else on steam deck.
