hey i just wanted to know that my father had a new toshiba satellite c55dt-a laptop and that it can go to touchscreen and i just remembered that osu can be played via touch screen. when i tried to play osu my cursor has some 0.5 to 1 sec lag even if i put my hand accurately into the note and i already put my response for clicking on my pen and touch screen to fast but it still doesn't work. anybody help me with the settings?
