Oh, you're correct, that's a mistake on my behalf. Enhanced pointer precision is always off. In regards to sensitivity, as long as the dpi doesn't go beyond the stage where pixelskipping becomes an issue, I can't imagine high dpi having negative effects in the long run if I adjust properly to the sensitivity. I have indeed only picked up Osu recently, but a lot of the technique will carry over from RTS gaming, which I've been doing for years.
