Aim Does Not Feel Smooth (Mouse and Keyboard)

Aiming on mouse and keyboard for some reason feels very jittery when trying to make small precise movements, making it very difficult to land shots at range sometimes. Even after adjusting numerous settings, the aim still doesn’t feel smooth when compared to MCC or other FPS games. Mouse Magnetism and Vsync are turned off and I play at 800 DPI with 1.6 sensitivity.

I realized I posted this on the wrong subforum, this was meant for the “Halo Infinite” forum. Could an admin move the thread?
