Driver interpolated CPI settings are fine for normal usage. Max speed is great too, only LOD is definitely better on the laser sensor, although in G400 it isn't uncomfortably high. Of course CPI over 3600 is nonsense. Actually I consider optical sensors a bit better than A9500 in terms of tracking at high CPI.
That certainly is the question. Most people aren't going to need
excessively high CPI and those that do likely have improper settings in the first place. I was merely just stating that I feel the A9500 has better tracking quality (ie non jitter) @ 3500 CPI and beyond. The 3090/3888/S3095 become very hardware (mp/s) / surface limited at that point.
But you're right. The greatest benefit of the A9500 (Sensei for example) is its lift off to tracking speed ratio. Custom lens' for optical mice work, but they tend to sacrifice tracking quality (IE jittery movements) as you scale higher and higher throughout it's CPI ranges.
The Logitech led and lens for example was developed durring an era when 800 CPI was peak and didn't really pose an issue to its tracking. Compared to Avago's solution I find logitechs setup a bit worse with current day CPI values.
Zowie's AM's Kingsis lens has a similar effect with it's 2300 CPI setting, you see?
Of course, this isn't going to matter if you purchased the mouse for it's lower CPI settings.
