The DPI button on the top of the Pugio allows you to quickly toggle between two preset DPI settings whenever you want to. While only being able to have two DPI levels programmed to the button at a time, there is a handy white LED just below the button, which lets you know when you've enabled a different DPI setting using the button.
The Pugio uses Asus's Armoury software to adjust the different functions of the mouse. Armoury is well-built and functional. Within the application, you can adjust key bindings, mouse performance (such as DPI, polling rate and button response time, to name a few), the all-important RGB lighting controls as well as surface calibration.
On top of the application's core functionality, you can also adjust macros, sync your Armoury devices lighting and record your mouse statistics.
There are 3 lighting zones on the Pugio, the ROG logo, scroll wheel and the base, all of which can be independently controlled or synced together. There are six lighting options for you to choose from and there is further room for lighting customisation.
Unfortunately, Asus' Aura lighting software, which is used to control Asus' motherboard, graphics card and other third-party devices with lighting that Aura support, is completely separate from the Armoury app. This means that you need yet another piece of software to fully control your peripherals. The Pugio is built as a device for everyone, for ease-of-use, yet this lack-of-integration makes the experience less user-friendly.
Asus' Armoury software received an upgrade this year with version two becoming available with Asus' new keyboard, the Strix Flare.
