— flagship optical sensor of the latest generation, featured in top gaming models of 2024–2025. It provides ultra-high sensitivity (up to ~30,000 DPI and higher in some implementations), high tracking speed up to 750 IPS, and acceleration up to 50G, so the mouse confidently "reads" even the sharpest flicks without skipping or cursor prediction. Compared to the popular PixArt 3395, the PixArt 3950 sensor offers slightly higher DPI, better tracking at high speeds, and more efficient energy consumption, which is especially important for lightweight wireless mice. It is commonly chosen by manufacturers of esports and ultra-light models designed for shooters and competitive gaming, where maximum precise flicks, stable cursor behavior, and no unnecessary processing by the sensor are crucial.
