Well, I'm getting well over 100 FPS in this particular room, but the sensitivity is still uneven.
What I mean is that when I'm looking up and down, it's way too sensitivity, but it's normal when I'm looking left and right. This is all while standing in place as well so I'm not actually moving from one area to the next when testing the sensitivity.
It is only with the heart that one can see rightly; what is essential is invisible to the eye.
it is especially annoying considering the vertical nature of the environment and i have yet to fight a dragon but i assume that fighting a giant flying creature will be very annoying when it takes 10 seconds to look up..
It feels like some sort of autoaim to me because even with turning off acceleration and making the X and Y the same it still happens when looking at objects that you can collect (on shelves especially).
