The lines you draw should appear instantly. Software stability: A drawing tablet’s drivers-the software that allows it to communicate with your PC-affect how well the tablet works with your computer, which software the tablet works with, and the presence and severity of input lag.All of our picks have at least 4,096 levels of sensitivity, though I tested one model with 2,048 levels and didn’t detect any particular deficiency connected to that. Most modern tablets range from 4,096 to 8,192 levels of sensitivity, but we’ve found that a minimum of 2,048 levels of pressure sensitivity (which scales upward in intervals of 512) is the lowest acceptable number. Pressure sensitivity: Many experts we’ve interviewed agree that pressure sensitivity is the most important feature of a drawing tablet.Reliable stylus detection: A drawing tablet should reliably track the stylus position, including along the outside edges of the panel or when you’re drawing quickly or in tight, circular strokes.
