Since Logitech features an unified software package, there's no need for an included disk. Instead, the packaging directs you to download the latest version online. With it, you can customize the backlighting, macros, swap around profiles, and if you have another Logitech G device, have the two peripherals interact with one another. Though Logitech lists it as optional, and the keyboard has no problems running with no installed drivers, the Software is mandatory to access the extra features.
The main window is the standard one, with a large graphic representation of the device selected, and small icons along the bottom bar. It's an easy-to-use software bundle, even though its buggy at times. Next to the peripheral-listing you have a number of tabs for key-configuration, backlighting, and lastly Key-Press Heatmap.
Since G910 features a total of nine dedicated macro keys: five to the left and four above the F1 through F4, these can easily be customized. Preset commands can be dragged from the menu to the left ont the graphic representation of each macro-key. The software also scans installed games and displays icons at the top-bar when you want to cycle through a certain series of predetermined commands for the selected games.
If you decide to customize said pre-determined commands, you just choose from the drop-down menu Edit, and that will open up the Command Editor featuring a number of options, from custom keystrokes and multi-key combos, to Functions, Ventrillo commands and Windows Hotkeys.
The custom backlighting settings for G910 feature a large representation of the mech to showcase how the lighting effect will look like. Under it, a simple menu contains a number of modes: freestyle, zones, commands, and effects. Each of these opens a certain type of sub-menu that contains the customziation options for the mech.
Zones allows you to create and assign groups of keys to share the same lighting color you prefer.
Command Lighting triggers a preset or user-defined key-lights when the game is launched (Note: said game must be recognized by Logitech Gaming software).
The Effects Tab contains several sub-menus for dynamic key-backlighting, including breathing & star Effect, color Cycle and color wave, each with their own small sub-menus.
The last is something I've also noted on Razer's Blackwidow, where you have a heatmap and KPM tool built into the software. A variant of this option you find on other Logitech devices like the G710+ or G510s. The difference is that here the backlighting will change according to the number of times you pressed said key.
After a recording session, the graphic won't change, but keys will change colors according to your key-presses, and a circular legend posted to the top right showses the number of key-presses and key-duration. The legend and graident can be changed by clicking one of the icons to the right of the legend.
