Ok his aim is actually insane like wtf??
A lot of my friends have high sens. I used to play Val using 1100dpi and 0.8 and the reason is that at that time I don't like to move my arm that much so I just used my wrist. Until the moment that my wrist started to hurt so I change it to 0.3
You are either kovaaks nova/astra or at least gm and radiant in val or you are hardstuck bronze 2 who will never get out because ur mouse control skills are way too bad to be able to handle ur sens.
and the highest is not f0rsaken or smth. its d4v41 with 900 dpi 0.65 (0.731 if u convert it to normal 800 dpi)
