The fresh new Pwnage StormBreaker has the PixArt PAW3395

Centered on criteria, new 3395 can perform doing twenty-six,000 CPI, and additionally a max record rate off 650 IPS, hence equals m/s. From the box, five pre-outlined CPI methods are available: eight hundred, 800, 1600, 3200, and you may 6400.

The comparison is actually complete to your newest firmware (V0133), apart from mouse click latency, which in fact had to get performed for the an older variation (V0120), as almost every other one has become affirmed becoming women slavic bugged in one to admiration. As such, overall performance received for the additional firmware products may differ off men and women shown hereafter.

CPI Accuracy

“CPI” (brief getting counts for every inches) identifies exactly how many counts inserted of the mouse if it was went just an inch. There are many circumstances (firmware, mounting level of your detector maybe not fulfilling needs, mouse feet thickness, mousing body, yet others) that may contribute to nominal CPI maybe not complimentary real CPI. There is no way in order to usually go a perfect matches, however, preferably, affordable and you can genuine CPI will be differ as low as you can easily. In this shot, I’m deciding whether or not this is basically the instance or perhaps not. But not, delight remember that said variance usually nonetheless change from device so you can device, so your distance may vary.

You will find restricted my investigations toward four most commonly known CPI actions, which can be 400, 800, 1600, and you can 3200. As you can plainly see, there is absolutely no departure anyway, which is the greatest impact.

Actions Impede

“Motion impede” encompasses a myriad of detector lag. Anymore types of input decrease will never be recorded when you look at the it decide to try. The most important thing I am going to be in search of in this sample is alarm smoothing, and therefore describes an averaging of movement analysis across the numerous capture frames in order to treat jitter at the higher CPI beliefs, increasing motion impede with-it. The prospective we have found to possess as little smoothing that you could. As there is not any treatment for correctly level actions decelerate definitely, it will just be done-by research with a handling topic that was calculated to have the lowest you can actions slow down. In this situation, the new handle subject try good G403, whose PMW3366 has no noticeable smoothing across the entire CPI assortment. Remember that brand new G403 is moved basic which means gets an effective moderate head start.

Very first, I am looking at one or two xCounts plots of land-produced in the 1600 and twenty-six,000 CPI-so you can rapidly gauge if there is certainly people smoothing, which may become indicated by any visible “kinks.” Neither plot reveals one kinks, firmly suggesting here not-being one smoothing.

New StormBreaker as well as allows providing MotionSync, and this effortlessly synchronizes SPI checks out with USB polls, causing very low SPI time jitter given that viewed a lot more than.

To help you determine action impede, I am looking at xSum plots generated at the 1600 and twenty six,000 CPI, each other as opposed to (basic row) and with (second line) MotionSync. Brand new range subsequent to the left denotes the new alarm that have smaller actions slow down. In place of MotionSync, there is absolutely no activity delay differential at the 1600 and you will twenty-six,000 CPI, and that verifies there is no smoothing across the entire CPI assortment. Enabling MotionSync contributes a movement decrease out of about 0.5 ms.

Not much change whenever running the StormBreaker inside the wireless function while the SPI time jitter and you may general recording are practically on the same top as the when wired.

Once again, 1600 and you may twenty-six,000 CPI one another in the place of (basic row) with (2nd row) MotionSync is actually checked. Versus MotionSync, a motion reduce differential regarding around 1 ms can be counted within each other 1600 and you may twenty-six,000 CPI. Which have MotionSync, a motion impede differential from 0.5 ms is actually added once more, leading to an entire action decrease differential of about step one.5 ms.
