Ok, so, since all the latest zowie mice got the same sensor and same sensor implementation as well as the same dpi steps levels, and since the sensor is "raw" 3310 (one of the latest sensor ever released), I'm tempted to think and ask myself "what would be the perfect dpi step, in term of snappiness/responsiveness/accuracy/'low inputlag'?".

I heard many times already that the 3310 sensor and above (3360/3366 etc) doesn't have any "native" dpi step, which basically means that it will work the same at ANY dpi step. Not sure about "jitters" at very high dpi settings though (basically any values above 2000dpi).

The dpi steps are 400dpi, 800dpi, 1600dpi and finally 3200dpi.
From my own experience, 3200dpi with ultra high sens (1-3cm/360) feels snappy enough without any "jitterness"; 400dpi with low sens (26cm/360, sensitivity 4 ingame, basically the current cooller's sens settings) just feels right too, except that ofc compared to high sens it feels slower, not less responsive, just slower (which is 200% logical considering it's a low sens); 800dpi with medium sens (~20cm/360), there again, the mouse just peforms as you would expect it to do, it's responsive, good feeling, no "jitter", everything seems fine; and finally my current settings 1600dpi sens 1.8 ingame (14.4cm/360), the settings i feel most comfortable with.

So basically, I tried pretty much every settings but failed at finding even the slight difference(s) between all those settings in term of "input lag"/"smoothing"/"snappiness" etc.
When people said 3310 sensor just performs the same at any dpi step, I tend to think it's true, from, like I said, my own experience but also the multiple threads etc I found on the internet. However, I'm no god when it comes to technical stuffs regarding mice, ofc I know the basics and further, but that's all. And I'm still asking myself "if I didn't find any notable differences, is it because I'm unable and not sensitive enough to "feel" them, or is it because there are obviously no notable differences at all?".

One last thing that makes me have doubts, is that pretty much all the pro players (be it CS:GO or Overwatch or Quake) use either 400dpi or 800dpi. Is it simply because they feel they don't need more dpi and/or they are using low sensitivities, or is it because actually these 2 dpi steps work the best with any zowie mice, in comparison to 1600dpi and 3200dpi ?

I'm worried because I might actually use the wrong dpi step (1600) just because I might fail at finding any noticeable difference(s) between 400, 800 or 1600 (like I'm not sensitive enough).

TL;DR do all 3310 zowie mice perform the same at all dpi steps (400, 800, 1600, 3200), or is it better to use them (the mice) at either 400dpi or 800dpi, if you want best responsiveness/snappiness/accuracy/etc ? TL;DR
