Previously Zowie used the A3090 sensor with mixed results, mainly because their Kingsis lens that lowered the LOD also reduced the perfect control speed. Also the polling rate was kind of unstable and somehow the tracking was better at 500 Hz compared to 1000 Hz on the lower steps. This never resulted in serious malfunctions for me (only in certain games with very fast movements, like rocket jumping in TF2), it’s just something that I was curious about with the implementation of the 3310 by Zowie. So has this been fixed? More about that later.
First to the 3310 in general: it’s the same sensor that is used in many new optical mice, like the Steelseries Rival, Mionix Avior or the Kone Pure Military. The sensor features native steps every 50 cpi and LOD customisation out of the box.
However Zowie sticks to their mantra of “no software”, so the FK1 can only be set to 400, 800, 1600 and 3200 cpi (with the button on the bottom of the mouse). This is no malus for me, but people looking for a lot of customisation have to look elsewhere. The customisable LOD of the 3310 also allowed Zowie to drop the Kingsis lens and go for the standard lens while keeping a low LOD.
