Just like last time, I used four different mice for testing: a Tt Iris Optical (PMW3325) and HyperX Pulsefire Core (PAW3327) to test some medium-tier sensors, and a Logitech GPW (HERO) and Ninox Venator (PMW3360) to check the performance of high-end optical sensors. Since the surface is pretty much perfect—smooth, and even—I didn't expected any malfunctions, and thankfully, I didn't come across any surprises during testing.
Ninox Venator - PMW3360
Logitech G PRO Wireless - HERO
Tt eSPORTS Iris Optical - PMW3325
HyperX Pulsefire Core - PAW3327
These graphs show some horizontal swipes, and if anything funky should happen with the sensor, this test indicates that. I also did some in-game testing with high-paced shooters and came across no anomalies whatsoever.
