i think the question:mouse dpi used by top level players? - is not correct!
Correct is:(interrelated things)
1) resolution (1440, 1024 or another, full screen, windowed)
2) mousepad (speed mousepad or precision mousepad, plastic or cloth)
3) dpi of mouse + ( osu sens, windows sens, accel, polling rate)
4) playstyle: mouse+keyb or mouseonly: mouse+keyb style players have DPI less then for mouse only
