New Pwnage StormBreaker is equipped with brand new PixArt PAW3395

According to requirement, the brand new 3395 is capable of as much as twenty six,000 CPI, and a max recording rates away from 650 IPS, hence translates to m/s. Out from the field, four pre-laid out CPI measures are available: eight hundred, 800, 1600, 3200, and you may 6400.

Most of the analysis is actually done towards newest firmware (V0133), except for click latency, which had is performed towards the an adult type (V0120), as the most other you’ve got started affirmed becoming bugged into the you to value. Therefore, efficiency gotten toward various other firmware versions may differ regarding those people demonstrated hereafter.

CPI Precision

“CPI” (short to have counts for every inches) means the number of counts entered of the mouse when it is actually gone precisely an inches. You can find issues (firmware, mounting height of your alarm perhaps not conference demands, mouse legs density, mousing epidermis, as well as others) that may join affordable CPI perhaps not coordinating real CPI. It’s impossible so you can always get to a perfect match, however, if at all possible, affordable and real CPI is differ as low as possible. Inside sample, I’m deciding whether here is the situation or otherwise not. Yet not, please understand that said variance usually nonetheless vary from product so you’re able to tool, which means your distance can differ.

We have limited my personal analysis into the four common CPI actions, being 400, 800, 1600, and you may 3200. As you care able to see, there’s absolutely no departure whatsoever, that is a perfect influence.

Action Decrease

“Motion decelerate” border a myriad of alarm slowdown. More resources of enter in slow down will not be filed within the it take to. It is important I’ll be in search of within this take to is detector smoothing, which makes reference to a keen averaging of motion study across the numerous grab structures so you can clean out jitter in the highest CPI thinking, broadening action decelerate with it. The prospective is getting only a small amount smoothing that one can. Because there is not any way to accurately scale actions reduce definitely, it does simply be carried out by comparison with a control topic which had been computed to get the reduced you can actions decelerate. In this situation, this new control topic try a good G403, whose PMW3366 does not have any kissbrides.com browse around here obvious smoothing across the whole CPI variety. Remember that new G403 are went earliest and thus gets a good limited start.

Very first, I am thinking about a couple of xCounts plots of land-produced in the 1600 and you may twenty six,000 CPI-so you’re able to rapidly determine if or not there clearly was people smoothing, that will become conveyed of the any visible “kinks.” None spot suggests people kinks, firmly indicating around not one smoothing.

The StormBreaker also lets enabling MotionSync, which effortlessly synchronizes SPI checks out having USB polls, ultimately causing really low SPI timing jitter given that viewed a lot more than.

In order to determine actions impede, I’m looking at xSum plots of land generated at the 1600 and you may twenty-six,000 CPI, one another instead of (first line) sufficient reason for (2nd row) MotionSync. Brand new line next left indicates new alarm with less motion reduce. Instead of MotionSync, there’s absolutely no action delay differential on 1600 and you will 26,000 CPI, and this verifies that there’s zero smoothing along side whole CPI assortment. Helping MotionSync adds a movement delay regarding about 0.5 ms.

Very little change whenever running brand new StormBreaker for the wireless setting because the SPI timing jitter and you may standard record is actually around on a single top due to the fact when wired.

Once more, 1600 and you can twenty six,000 CPI one another rather than (first row) in accordance with (next line) MotionSync are checked-out. Without MotionSync, a motion decelerate differential out of approximately 1 ms shall be mentioned from the one another 1600 and you can 26,000 CPI. That have MotionSync, a movement slow down differential out of 0.5 ms are extra again, causing a complete motion slow down differential from about 1.5 ms.
