One tip here for everyone the different I personally found between 1000hz and 500hz I will test out 250hz and 125hz soon
1000hz = more precision and smooth movement in slower sens but in higher sens I cannot aim
500hz = less precision relatively smooth movement, but allows you to play in higher sens stutter-free.
