The DeathAdder Elite introduces a new “5G Optical Sensor” that’s capable of tracking up to 16,000 dots per inch (DPI) at 450 inches per second (IPS). Razer claims the DeathAdder Elite has the highest resolution accuracy ever recorded in a gaming mouse at 99.4%. You will rarely — if ever — use the mouse at its peak sensitivity but we can tell you after using the Elite for a few weeks that it tracks movement with flawless accuracy.
