Although it can only go as high as 4000DPI (which is quite low compared to the 12000DPI of the G502 Proteus Core) Logitech markets the G402 Hyperion Fury as the fastest FPS gaming mouse in the market currently something which they have accomplished by pairing their Delta Zero Sensor Technology (we’ve already seen it with the rather new G602) which increases precision with their Fusion Engine Hybrid Sensor which basically makes use of an gyroscope and an accelerometer to “predict” the heading/position of the mouse (a technology also used in satellite navigation).
