Sensor

HyperX knows that sensor performance must be maximized in order to create an eSports-ready mouse. Hence, they used the PixArt PMW3389, one of the best optical sensors out there. It was originally patented by Razer as a PMW3366 variant, but since the patent expired, quite a few companies have used this sensor in their mice, which is no wonder as its performance is truly remarkable with a good implementation.

The nominal maximum tracking speed and acceleration values of this sensor are as high as they get at 450 IPS (5.5 m/s) and 50 G. The resolution can be set from 100–16,000 CPI in increments of 50 CPI, and the only available polling rate is 1000 Hz. There are no angle snapping or lift-off distance adjustments either—the latter is below 1 DVD in height as measured on a black cloth mouse pad.

Paint Test

There is no jitter on the reasonable CPI steps, or unwanted angle snapping and measurable (or audible) sensor lens rattle.

CPI Divergence

CPI divergence on the HyperX Pulsefire Surge is "just the usual" with the measured values are slightly higher than the nominal ones. Please note that this test is not 100% accurate, but it resembles reality well.

Perfect Control Speed

Perfect control speed is insanely high; the nominal value is 450 IPS, which is over 11 m/s. There is absolutely no chance of hitting this value in-game, on the desktop, or anywhere else within the mouse's proper application area.

Speed Related Accuracy Variance

This test shows the sensor's accuracy at different speeds. You can see me doing a fast swipe to the right before I slowly slide the mouse back to its original position. There is no acceleration or deceleration; any displacement is almost entirely caused by human error in this test.

Polling Rate

The 1000 Hz polling rate seems to have some outlier spikes here and there, but I did not find this to be an issue while gaming with the mouse.

Input Lag

There is no input lag below 1,800 CPI. The smoothing kicks in and stays at about +2 ms until the 5,000 CPI step. Above that value, it linearly increases and reaches about +10 ms with 16,000 CPI. These values represent the average PMW3389 implementation as far as I can tell. +2 ms is really nothing to worry about—I'd highly suggest staying on or below the 1800 CPI value if you're a competitive player, though.

Click Latency

The click latency is roughly +10.5 ms when compared to the SteelSeries Ikari, which is considered as a baseline with 0 ms. The control subject was a Logitech G102 (with a covered lens). The data comes from this thread and from my own testings. The test was done on firmware version 1.1.1.4; as far as I know, the previous firmware has a +5.2 ms value.
