Software

The Strix Impact II is compatible with ASUS' ROG Armoury II software. Options include button remapping (mouse, keyboard, media, and macro functions), CPI adjustment (100–6200 CPI in increments of 100 CPI), angle snapping (on/off), polling rate (125/250/500/1000 Hz), button debounce time (12–32 ms in increments of 4 ms), and a basic acceleration/deceleration function. Macro support, profile management, and a stats recording feature are available as well. On my system, the software had a RAM footprint of 95 MB on average. Even upon terminating the software, a surprisingly large number of processes keep running, totaling 42 MB worth of RAM usage. In fact, these processes run on every system startup and cannot be disabled.

Lighting

The Strix Impact II has three zones for RGB lighting: scroll wheel, logo at the back, and the "grill" at the front. The three zones can be operated independently; i.e., while having the Color Cycle effect run on the scroll wheel, Breathing can run on the logo (or vice versa). Through the software, four pre-defined lighting effects are available: Static, Color Cycle, Breathing, and Reactive. Furthermore, lighting brightness and color intensity/saturation can be adjusted. Selecting 0% brightness will disable the lighting altogether.

Color accuracy and vibrancy are excellent throughout. Here's a short demonstration video of the Color Cycle and Breathing lighting effects:
