First it's settings not real numbers. I'm not claiming that's how the mice actually perform, only how I tell them to perform.

Second 3200 was DPI not Hz. I can trivially tell how much I have to move with 3200 DPI (my sweet spot with 2 4K monitors), 4800 DPI, and 6400.

For Hz, it was the polling rate. With a configured 8000 Hz polling rate which is a lie/peak, I still see stalls in the 4ms range with my hardware.

As to acceleration I disable it. To truly lose it at high DPIs I've had to install RawAccel on Microsoft Windows.
