At the default 'Very Low' setting, the sensor does not track at a height of 1 DVD (<1.2 mm).

Lift-off DistanceThe Burst Pro offers two pre-defined LOD levels to choose from, along with the option to manually calibrate LOD. Lastly, there is no sensor lens movement. 16,000 CPI shows high but not excessive jitter. No jitter is visible at 16 CPI, the latter of which already has smoothing applied. As you can see, no issues with angle snapping can be observed. This test is used to indicate any potential issues with angle snapping (non-native straightening of linear motion) and jitter, along with any sensor lens rattle. However, please keep in mind that said variance will still vary from unit to unit, so your mileage may vary. In this test, I'm determining whether this is the case or not. It is impossible to always achieve a perfect match, but ideally, nominal and actual CPI should differ as little as possible. There are several factors (firmware, mounting height of the sensor not meeting specifications, mouse feet thickness, mousing surface, among others) which may contribute to nominal CPI not matching actual CPI. As such, results obtained on earlier firmware versions may differ from those presented hereafter.ĬPI Accuracy'CPI' (short for counts per inch) describes the number of counts registered by the mouse if it is moved exactly an inch. Out of the box, five pre-defined CPI steps are available: 400, 800, 1200, 1600, and 3200 CPI.Īll testing was done on the latest firmware. According to specifications, the 3389 is capable of up to 16,000 CPI, as well as a maximum tracking speed of 400 IPS, which equals 10.16 m/s. The drastic differences between mouse buttons might throw some users off since a different amount of force is required to activate each button.Sensor and PerformanceThe ROCCAT Burst Pro is equipped with the PixArt PMW3389. Meanwhile, the scroll wheel has some noticeable tactility but produces little to no sound. The mouse one and two buttons are on the opposite side of the spectrum, featuring a weighty and tactile click with an odd, almost hollow tone. The side buttons are hyper-sensitive and have a softer, more muted tone. Buttons feel drastically different from each other. All of the included buttons use ROCCAT’s Titan optical switches. Included on the Burst Pro are the usual six programmable buttons. Some may be critical of the lower DPI range, but it never became an issue, and there weren’t any noticeable performance hiccups.

While other high-end gaming mice feature sensors capable of up to 25,000 DPI, there’s really no need to go near the high end of your mouse’s DPI range unless you enjoy missing shots.

ROCCAT’s Owl-Eye optical sensor is capable of up to 16,000 DPI.
