Sensor

Most MMO-oriented mice still feature outdated sensors; these often are VCSEL sensors, such as the A9800 and A9500, which are inferior for some proper precision work and higher velocity gaming. Thermaltake eSPORTS took the opportunity and released the Nemesis Switch with the current flagship of optical sensors, the PixArt PMW3360. It is raw, responsive, and pretty much gives a 1:1 tracking feel. I really do hope more companies will follow the example of Tt eSPORTS as it is plain nonsense to still feature subpar sensors in their most of the time ridiculously overpriced MMO models. The MCU used here is a 32-bit ARM Cortex-M0-based PT32C302 manufactured by PTC.

The resolution can be set from 100 to 12,000 CPI in increments of 100 CPI. The available polling rates are 125, 250, 500, 1000, 1500, and 2000 Hz. There is an option to adjust the angle snapping, but for gaming and precision work, I would highly suggest turning it off. The lift-off distance has levels ranging from 1–10, but you can also manually calibrate it to your surface. Generally, lower is better here, so you should use the lowest setting that doesn't cause any malfunctions on your specific mouse pad. Also, there is an option to reduce the button response time with a slider, and I would highly advise bringing this down 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 is pretty good, but I have seen better. Deviations are definitely not as high as in the case of the Ventus X Optical.

Perfect Control Speed

The perfect control speed (or PCS for short) of the PMW3360 sensor is very high. It is approximately 6–7 m/s depending on the surface and the sensor's implementation. There is absolutely no chance of hitting this value in-game or anywhere else accidentally, so you don't have to worry about spin-outs with even huge swipes across your mousing surface.

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 with some minor outliers that are most of the time measurement errors. The 1500 and 2000 Hz values cannot be properly measured with the current software unfortunately, but their average value was correct with the MouseRateChecker tests. Honestly, I don't see the reason to use polling rates that high; 1000 should be more than sufficient for everyone (and we'll see what the future holds).

Input Lag

Just like the other mice equipped with the same sensor, the Nemesis too "suffers" from the smoothing issue above 2000 CPI. This issue results in +2 ms of input lag, which most of the time isn't noticeable, but if you are a competitive gamer, I would highly suggest staying on or below that resolution.
