Sensor and switches for fast play
The Focus Pro 45K sensor tracks at up to 45000 DPI and handles up to 85 G acceleration, so the cursor stays steady even on very sharp moves. The fourth-generation optical switches register clicks with a light beam, and Razer rates them for 100 million clicks. The scroll wheel is optical with 24 steps. These specs come from the listing of the same model in its NiKo Edition.
