You can choose to have more or less samples per layer of display. More
samples will make a more precise measurement, but it takes longer to
achieve. The refresh rate will change depending on the number of samples
selected.
To select the number of samples:
1. From the main window, select the Display menu, then Samples /
Layer.
2. Select the number of samples to use.
