More data and counts to allocate for. The 3500 Step of the specific sensor/rom is fairly "raw" and subject to what is defined as ripple or commonly referred to as "jitter" when updated every 1000/1000 or 1ms (And even 1000/500 or 2ms). Hard limiting the amount of data passed to a lower timestamp will essentially help smooth out and interpret hand movement quite accurately though response rate is of course lower.
- 1000hz is fine till around 800 or so CPI on most higher end
gaming grade CMOS sensors. (ex. DA, G9x)
- The DA's default settings of 1800 and 500hz work fairly good. Not much ripple, though also very fast in terms of response rate.
- Faster response isn't always better (whether that be 500 or 1000hz) Input lag of your monitor could impose in terms of hand and eye coordination. While I wouldn't have imagined using 125hz on my older LCD, I kind of have to on my current 120hz to compensate for lag. -.-
The whole CPU stress is a invalid point if you're playing games in 2012 ^^Edited by Skylit - 10/24/12 at 4:17pm
