Up until the latest 3.00.17 firmware at polling rates above 6400 the sensor was a complete mess. There was a lot of acceleration and jitter on small movements. The latest firmware improves this a lot and I have seen the results in game. However, it still has an issue picking up the smallest movements which you wouldn't expect at a polling rate of 42000. If i try to do slow pixel circular movements the result ends up boxy at best and I don't have angle snapping on. Hopefully they aren't done working on this mouse because the last firmware was a huge improvement to motion at higher DPI.
