Here is the announced key features of Proteus Spectrum
Accurate and responsive optical sensor: The Logitech G502 Proteus Spectrum features a powerful and accurate optical sensor, the PMW3366, for maximum performance and tracking accuracy. Increase your reliable targeting with our exclusive Logitech G Delta Zero™ optical sensor technology. The Logitech G502 Proteus Spectrum also features a huge DPI range of 200 to 12,000 with zero sensor acceleration, zero smoothing or filtering, and zero pixel rounding.
Surface tuning calibration: For optimal performance, calibrate the sensor against a gaming surface’s physical and reflective characteristics. Surface tuning optimizes the sensor dynamic range to match the properties of the mouse surface, which results in maximum high-speed performance and lower lift-off distance.
Weight and balance tuning: The overall weight, as well as the center of balance of the mouse, can be customized based on the placement and number of a series of small weights. Add up to five 3.6g weights for personalized mass and balance.
11 programmable buttons: Great in default mode, but built to adjust to your style, the Logitech G502 Proteus Spectrum lets you set up one-button triggers, put push-to-talk in easier reach, temporarily down-shift DPI for sniping, or reassign any command or macro to one of the 11 programmable buttons.
RGB customizable lighting: Match your style and environment by adjusting the mouse’s lighting with up to 16.8 million colors. Bring your mouse to life with breathing light patterns, or set your lighting to sleep when you aren’t using your system.
Easy-to-program Logitech Gaming Software: In addition to syncing colors and light patterns with other Logitech G RGB gaming products, use LGS to tune its sensor to match your surface for maximum speed and lower lift-off. Program buttons with custom macros.
Dual-mode hyper-fast scroll wheel: Logitech’s exclusive dual-mode scroll wheel gives you enhanced click-to-click precision for gaming and blazing scrolling speeds for the Web.
Comfortable shape: Textured rubber grips and a convenient button layout give you great feel and performance.
We are particularly interested in the RGB customization lighting. We wonder if the lighting change with the desktop color scheme? That way it will be really interested.
