improve response for drawing, touchesbegan touchesmoved

[thephotographer]

Hi,

im wanting to improve the performance of my drawing. i have a image loaded, and can draw lines. in the touchesbegan i save the start location, and in touchedmoved, i draw a line from the start location to the currentlocation.

if i move my finger quickly in an arc across the screen, a very sharp arc is drawn on the screen, depending on how fast i move it can have as little as 2 straight lines to make the arc representing where i dragged my finger.

what i need to do is lower the time between when touchesbegan is called, and when touchedmoved is called. the actual time to redraw isnt the issue, just how slow it is to call touchedmoved. normal use its fine, its just when you move your finger pretty fast it cant keep up, but i would like to make it as responsive as possible.

is there a different method i need to do?
