The ROG Gladius II Origin is equipped with a PixArt PMW3360 sensor, boasting a whopping 12000 DPI, 250 IPS tracking, and 50Gs of acceleration. This sensor is used in a lot of high-end optical mice now and translates to consistent performance for even the harshest, lowest DPI, screen-crossing flicks. If you stick to under 2000 DPI you’ll stay away from any sort of jitter, but even at higher DPIs the jitter is barely noticeable if you’re not doing super precise work or competitive FPS. Liftoff distance is customizable, but default settings should work plenty fine for most people.
The lighting features of the ROG Gladius II Origin are well executed and customizable in three separate zones – Scroll wheel, ROG logo, and the underglow. You have 4 brightness settings and full RGB colour control. Colours are vibrant and smooth, even when cycling through the RGB spectrum. I am a fan of purple myself and was able to select a nice deep purple without seeing any red or blue bleeding through.
If you are more invested in the ASUS ecosystem, you may be able to take advantage of Aura Sync to perfectly match up lighting between peripherals, video cards, motherboards, and other components.
