Thanks, very interesting stuff.
I've never heard that interpolation adds latency--you're saying it's about the difference between 500hz and 1000hz, which does concern me a bit. The lowest dpi step has
indeed been reported to have noticeable input latency.
Why wouldn't Zowie use native dpi steps?
Also, would only 2300 dpi really cause jitter? That's pretty low. I'd try the middle step, but I'm already using a pretty high in-game sensitivity (3.33 at 2300 dpi) and I don't want to start skipping pixels. Of course, I'd like minimal latency, too.
Despite all this, I do prefer the Zowie's tracking to the SteelSeries Rival (3011 sensor) and Deathadder 2013, as the smoothing on those is noticable--and according to the linked thread the g400 is just as bad, in that respect.
I'd really like to know if there's a mouse with superior tracking before I get too invested in the EC2. Do you have any particular recommendations? Any insights into the Kone Pure Optical?
From most reports I've seen, jitter is only really noticeable at the 2300 step; here are some Paint tests (courtesy of takasta in his FK review), it can be hard to discern with just images and ultimately it's if the jitter is an issue for you or not. http://www.overclock.net/t/1369780/lightbox/post/19486394/id/1342727/user/282230
I've never much looked into why Zowie utilizes these DPI steps in particular, mainly just looking at the mice themselves to see if I'm interested. Sorry I can't answer that.
Yep, the smoothing on the Rival and DA 2013 is noticeable. The g400 has a flawless sensor, it's the updated g400s (with the new and "improved" Delta Zero firmware) which adds the 4000 DPI step and, simultaneously, some smoothing to the mouse.
For recommendations, anything with a flawless sensor, including Zowie. If you're looking to avoid that latency, any mouse using the standard DPI step setup should work. I currently use the Roccat Savu myself, in preference of the Kone Pure Optical since I have to be a little picky on shape due to fingertip gripping. G400, Savu, Kone Pure Optical, Kana V2 are what I'd recommend; all of them have some varying minor issues which may be a big deal for you, I'd say look into these, if you don't like them than the EC2 is good, Zowie does make quality mice and the sensor issue is so minimal I wouldn't make too many sacrifices just for that.
