I am very reasonably dexterous, or even perhaps better than average. But I am having problems in aiming with the controller. After testing different settings, at the moment I have the look sensitivity set to maximum, as in 10. That said, there seems to be only two settings on the right thumb stick: either move slowly or sudenly very fast. There is not much in-between. Aiming down sight is even worse. So typically I either cannot track the target fast enough or my aim is suddenly all over the place. My complaint is that the aiming is not gradual enough - it is like a curve, starting off flat and suddenly spike upwards. What have I done wrong? How can I improve? Please advise. Many thanks!
