Highest frame per second optical sensor. - Page 3

post #21 of 23
Well, the STMicroelectronics sensor in a Hades H8 Phorcy runs at 12,000 FPS (and up to 3200 dpi), but in my opinion, it's not as good as an Avago 3090. The Phorcy's sensor is very surface-sensitive, a bit jittery-- perhaps due to it considering my mousepad less than 100% perfect, and therefore objectionable-- and runs into negative acceleration when moved rapidly (which may or may not be in some way related to the fact that the Phorcy tends to run at polling rates far less than whatever it's set to; I've heard that there is a firmware fix for the issue, but it's not downloadable, and I'm not about to ship a mouse that isn't even my primary all the way to Taiwan for a fix that may or may not make a difference).

Went through a handfull of ST datasheets. Highest specified frame rate was 10000.

Either something I missed or this specific mouse is set over parameters? false spec? All use a rather small 20x20 pixel map. ( Comparison A3050 = 19x19)

Don't you think that sensor 6000 or 9000 FPS isn't that important if mouse is polled only 125 times a second and you see on screen result even less frequently?

May effect feel to an extent.

Only way to really figure that out is to purposely lock (non dynamic) and set a specific max registry. I had some time with a mouse set to a lower fixed registry. Felt laggier than what it was designed for.

Tracking algoritm outside of actual hardware models is greatly underestimated. Can make or break a specific sensor design.

I wouldn't be surprised if it turned out they were trying to push the sensor beyond spec (and not entirely succeeding).

Unfortunately, I can't find any specific information about what model of sensor it is; it just calls it (after looking around the web for the characters on the label and then running them through Google translate) a "STMicroelectronics ultra-high-end gaming optical engine".
