No jitter as long as you use the 2 deadzone config. I tested this with 2 mouses. I recommend 3200 DPI, 1000hz, off sync (4 smoothing).
Wether the optimal value is 1.5x, 3.7x, 6x, 10x idk mentioning random numbers I am definitely feeling a more responsive aim assist. To find that number is gonna take some testing.
