Swamp cursor seems to be fixed in 3.38 firmware.
I tested Avior 7000 vs the following mice: G400 (3600 DPI version), Kana v2, G502, G402
I used League of Legends to test 2d play since it has a very lightweight engine, and Crysis 3 for 3d play for the sole reason that it's what I'm playing through right now. Kana v2 and Avior 7000 come out on top in League of Legends with a big asterik for G400 explained below, and another asterik for G502. It will be down mostly to preference where the Avior has better precision, but heavier and a little more cumbersome, while Kana v2 has pretty much the exact physical dimensions and weight for what you would want in MOBA/RTS play.
In 3d engines where you pan the camera around in first person view, the Avior comes out ahead of the Kana v2 due to higher sensor frame rate and resolution giving you higher accuracy. The higher frame rate also seems to help in 1st person camera pans to make movement smoother as well as internet scrolling. The G402 I consider inferior to the original G400 in just about every way except maybe the shell, so I don't really need to go into that.
If I had to make a complaint on the 3.38 firmware, it would be that it feels like the mouse's anti-jitter protection might be clipping/clamping values a little too hard (whatever terminology you want to use), but there is not a heavy smoothing element to it. The mouse does feel a good bit different to earlier optical mice. Earlier opticals have a bit of a rubberband effect feel to them, while the Avior feels like a laser beam glued to the screen. I personally prefer the slight rubberband effect feel myself because it helps for flick shots. That feel might return somewhat if the clamping on the anti-jitter protection was loosened some, but I would have to test the differences between each firmware to see if it helped or hurt this particular sensor.
Having said all that, the cursor does not feel remotely similar to an MLT04 or anything. It feels more similar to a G502 with less buggy software or a G9x without acceleration.
*My original G400, which had some of the best performance of any newer generation mice I've used at 400 or 800 DPI & 1000hz broke and I'm now using a G400 imported from Korea. The new mouse does not perform similar to the old one. People like Skylit seem to post several times a day how manufacturing differences create mice that perform differently and this is definitely a case of that. In the past, I owned two Deathadder 3G at the same time where one tracked perfectly and the other tracked mediocre, so this is an example of that.
**The G502 has some kind of buggy software or firmware where each time you install the software to load settings, the mouse will feel completely different each time with no consistency whatsoever even when inputting the same settings. If I load the exact same settings in all three profiles in on-board memory, the mouse also feels completely different in each one. Profile three will also bug out and switch back to 500hz even when I set 1000hz. I'm not a fan of LGS and wish they would use different software for each mouse because it doesn't seem to be working. Razer Synapse is also a disaster.
