Daedalus Apex

RGB Performance Edition Gaming Mouse




Advanced Optical Sensor with Delta Zero technology

Superior tracking for precision movements

At the core of G303 is our best optical sensor, the PMW3366. Built with Delta Zero™ technology, it delivers exceptional tracking while minimizing speed-related accuracy variance, commonly known as “mouse acceleration”, allowing for quicker reactions and more consistent targeting. For maximum responsiveness, the PMW3366 sensor has zero smoothing or filtering across the entire DPI range—even at high sensitivity. The sensor can be tuned, optimizing sensor parameters, not just LED intensity, to match the properties of your mouse surface for maximum high speed performance and lower lift-off distance.
