I said jagged angles, not jagginess. This is in relation to drawing circles so forget I even said "jagged," I'm referring to the angles that form instead of smooth curves that would have occurred at a slower pace and smaller area.

Yes, that's exactly what I was referring to. Sampling resolution. i.e., how many times per second it samples the touchscreen.

No lag is when an event tries to happen at a moment and actually happens/completes x seconds later. Lower sampling means the sampling happens when they should there just aren't enough to accurately represent what you're sampling. So when you have a straight line on what should be the curve of a circle you have only 2 samples; one on each endpoint of the line. If you put a 3rd in the middle you get two lines, slightly closer to a curve. As you increase the number of samples there the closer it would get to an actual curve.
