Options/ Mouse auto looks

so when i play the game the game is smooth for me. But when i look around sometimes the game lags a bit then my guy just looks up or sideways for a sec and ya. its not my mouse ive tried other mouses in my house. also i can run the game its just, the character sometimes looks around or i would say i swipe to the left then i look a little but then a few secs later he keeps looking left with my hand off the mouse?
