RML, I tried using this quick setup, but the problem is that my xim flashes red almost all the time. Do you experience the same? And do You play tpp or fpp?
First of all I reworked this cfg to my liking.
I've been using GitGud's cfg with your curves for some time. It was butter, but than it became trash after some update, the jitter was insane and mist reworked St finallyfor all of us. I used it with 12k dpi and 1k hz.
Now I still use the curves, butmy cfg is like that : 4k dpi, 1k hz, common sync, sensitivities around 22(higher value,due to less dpi), AA on 5 and the rest is almost the same as yours, cause scope sensitivities are user preference for me.
To the point we go- by making it at 4k dpi I succeded in avoiding the jitter when u put your mouse back to the 'ground' (mousepad middle) after a turn or so. Cause on my screen with 12k dpi and Rival 310 i had jitter until mh mouse was sticked to the mousepad once again.
To avoid 'max turn speed' at all times i still use curves in hip and ads. It allows me to change target with different speeds, not max speed at all the time. If u adjust sensitivity to your liking, that allows You to build a muscle memory for all moves, from slow ones to ultra fast ones.
Think about it

Edit: sory i have not read all of the posts here, i just saw that u were already talking about it already. I was top 50 on duo's in tpp eu recently. This setup that I wrote above is butter for me now, I did 11 kills by myself on 3man squad yesterday, easy. Dropped 4-5 people in like 20 seconds with just akm on red dot in close quarter. Try that, maybe it will work for You as well as it does for me
