Software

Much like most other recent Cooler Master releases, the MM310 is compatible with MasterPlus+, which is also referred to as MasterPlus, but not to be confused with MasterPlus, which is older and incompatible with the MM310. There are separate pages for buttons, performance, lighting, macros, and profiles. All buttons except the left main button can be rebound, either to mouse, keyboard, macro, media, or OS functions. Additionally, Mouse Combo allows one to assign further functions accessible upon pressing a dedicated shift button. CPI adjustment is possible for up to seven levels and a range from 200 to 12,400 (interpolated past 6200), along with the option to adjust x and y-axis values separately. Further settings include polling rate adjustment (125, 250, 500, or 1000 Hz) and angle snapping (on/off). Furthermore, button response time can be adjusted from 1 to 6 ms.

All settings are updated live and saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, the software has a RAM footprint of around 355 MB on average when running in the foreground, which doesn't change when minimized to the system tray. Upon exiting the application, a single process with a RAM footprint of 5 MB keeps running.

Lighting

The MM310 has two physical zones for RGB lighting, which are the scroll wheel and logo at the back. A total of five pre-defined lighting effects are available in the software: Static, Breathing, Color Cycle, Electric Slide, and Trigger Click, accompanied by the ability to create a custom effect. For most effects, it is possible to set custom colors and adjust brightness as well as transition speed. Of course, disabling the lighting altogether is also possible.

Color accuracy and vibrancy are excellent throughout. Here's a short demonstration video in which I go through the Color Cycle and Breathing lighting effects:
