Centered on needs, the latest 3395 can perform doing twenty six,000 CPI, along with a maximum recording rates out of 650 IPS, hence means m/s. Out from the container, four pre-laid out CPI actions come: eight hundred, 800, 1600, 3200, and 6400.
Most of the testing is done to your newest firmware (V0133), apart from mouse click latency, which in fact had becoming performed with the a mature type (V0120), since almost every other you have already been confirmed is bugged in the you to definitely respect. As such, efficiency obtained on the some other firmware designs may vary away from the individuals presented hereafter.
CPI Reliability
“CPI” (brief to have counts for every single inches) means the number of matters joined by mouse if it are went just an inch. You will find some points (firmware, setting up level of alarm perhaps not conference requirement, mouse legs density, mousing body, among others) that may contribute to affordable CPI not complimentary actual CPI. It is impossible to help you usually go the best matches, however, preferably, affordable and you may real CPI is always to differ as little as you’ll be able to. Contained in this shot, I am choosing if or not this is basically the case or perhaps not. Yet not, excite understand that told you difference have a tendency to nonetheless differ from product so you’re able to unit, so that your usage can differ.
I’ve restricted my testing into the four popular CPI methods, which can be eight hundred, 800, 1600, and 3200. As you can tell, there is no departure whatsoever, that is a perfect result.
Activity Impede
“Actions slow down” encompasses all sorts of sensor lag. More sourced elements of enter in decrease will not be submitted into the so it attempt. The most important thing I am in search of within sample was alarm smoothing, which refers to a keen averaging of motion analysis across the several get structures so you’re able to dump jitter on large CPI thinking, growing actions delay along with it. The prospective here is to own as little smoothing you could. Because there isn’t any way to accurately measure actions reduce undoubtedly, it can just be done by comparison with a processing topic that was computed to get the reduced it is possible to action reduce. In this situation, brand new handle subject was a G403, whoever PMW3366 has no apparent smoothing along the whole CPI assortment. Remember that the new G403 was went first and thus gets good limited head start.
Very first, I am deciding on a couple of xCounts plots-produced from the 1600 and twenty-six,000 CPI-to help you quickly gauge if there can be one smoothing, that would feel expressed from the people visible “kinks.” Neither plot reveals any kinks, strongly recommending truth be told there not being one smoothing.
The newest StormBreaker together with allows providing MotionSync, and therefore efficiently synchronizes SPI checks out that have USB polls, ultimately causing low SPI time jitter once the viewed above.

To help you influence activity slow down, I am thinking about xSum plots made at the 1600 and you can twenty six,000 CPI, each other without (basic row) sufficient reason for (next line) MotionSync. New range subsequent left denotes brand new detector having shorter motion slow down. Instead of MotionSync, there is no action delay differential on 1600 and you will twenty-six,000 CPI, and therefore verifies that there surely is zero smoothing along the entire CPI variety. Providing MotionSync contributes a motion decrease regarding more or less 0.5 ms.
Very little alter when powering the fresh StormBreaker for the cordless function because SPI timing jitter and general recording is around for a passing fancy height since the whenever wired.
Once again, 1600 and you may twenty-six,000 CPI both versus (basic line) with (2nd line) MotionSync is actually tested. Instead MotionSync, a motion impede differential regarding roughly step 1 ms would be measured from the one another 1600 and you will 26,000 CPI. That have MotionSync, a movement decelerate differential out of 0.5 ms was additional once more, resulting in a complete activity decelerate differential of roughly 1.5 ms.
