I ' ve been a controller person my whole life . There ' s the main part of your answer right there . You don ' t switch to an entirely different control scheme than you ' ve been used to until then and expect to instantly master it . The movement is different , the aiming is both faster and more precise , it ' s an entirely different kind of muscle memory , and you ' re also losing the aim assist you have on console . That ' s a lot of habits to change at once . Which is odd , because I ' m told by literally everybody that aiming on PS 4 is terrible compared to PCHence the aim assist . You don ' t have that on PC , so you ' re basically losing your training wheels . Could it be my sensitivity ? There ' s that too . Hopefully you ' ve already disabled mouse acceleration , then it ' s about finding out what sensitivity works for you . Which depends on a ton of things including the size of the mousepad , but if you want to be precise , err on the side of a lower sensitivity . And don ' t use max dpi just because you can , there ' s no point . It ' s bugging me since I ' m supposed to aim way better with these hero ' s yet I ' m 10 x worse . You get worse before getting better . Even by staying on PC , whenever you change your mouse or decide to change your sensitivity , you go through a phase of aiming like crap before retraining your mechanics and getting hopefully better . So don ' t give up and keep at it . You will get better . Also , use the practice range and custom games with bots to practice more efficiently . Don ' t just throw yourself in real games right away . You ' ll progress slower and it ' ll be much more frustrating . Edit on that last note , Ie 5446 fSvcY is a pretty nice video with simple aiming exercises to make sure you ' re doing things right and are not trying to go too fast . Useful when trying out different sensitivity settings as well .
