Sensor

Tt eSPORTS didn't compromise on the sensor, using the absolute best optical sensor currently available—the PixArt PMW3360. It is raw, responsive, and gives 1:1 feedback. The firmware is nicely written too; I could not find any firmware-related issues anywhere. Of course, this mouse suffers from the same issue as all the other PMW3360-equipped mice out there: smoothing above 2000 CPI generates 2 ms of input lag. More on this a bit later. The nominal maximum tracking speed and acceleration values are 250 IPS and 50 G.

The resolution can be set from 100–12,000 CPI in increments of 100 CPI. The available polling rates are 125, 250, 500, and 1000 Hz. There is an option to adjust angle snapping, but for gaming, I would highly suggest turning it off. The lift-off distance has three available settings; low, medium, and high. The lowest does not track at 1 DVD in height (about 1.2 mm or 0.05"), and the highest setting barely tracks from 2 DVDs. The medium setting is between both of these as it tracks from 1 DVD in height, but doesn't track at all with two. Generally, lower is better, so you should use the lowest setting if it doesn't cause any malfunctions on your specific mouse pad. Also, there is an option to reduce the button response time. I would highly advise setting this slider to the minimum setting of 4 ms.

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 accuracy could be better as the deviations are moderately high. However, I wouldn't call this a deal breaker as you can adjust your in-game sensitivity accordingly.

Perfect Control Speed

The PCS of the PMW3360 sensor is insanely high; it is about 6-7 m/s depending on the surface and sensor's implementation. There is absolutely no chance of hitting it in-game or anywhere else accidentally, so don't worry about spin-outs on even huge swipes.

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.
Any displacement is almost entirely caused by human error in this test.


Here's the same test done with the MouseTester software.

Polling Rate

The set polling rates are nice and stable, but the 1000 Hz value shows some outlier spikes. They are probably measurement errors as I have not seen these affect my gameplay at all.

Input Lag

As most mice equipped with the PMW3360 sensor, the Ventus X Optical RGB suffers from the smoothing-related input lag issue above 2000 CPI. It is not much, only about +2 ms, but I would still suggest staying on or below 2000 CPI if you play multiplayer games on a higher level.
