Logitech Gaming Software
Once LGS has been downloaded and installed, the image above is what you see first. In this part of the menu, you may select either to use the onboard memory of the mouse for a defined profile, or by throwing the switch, you can have it look for a file on the PC, but only one profile can be on the mouse at any given time.
Moving to the right of the home menu icon, we find where to remap the buttons by clicking on any of the buttons with the right click, and with the dropdown box, select what you wish to do with it. Under the title of pointer settings, you can set the number of DPI levels to cycle through, and set each in 50 DPI jumps on your way to 12,000 DPI, either by dragging the bars or entering numbers into the boxes. You can also set the polling rate for use with HI mode power. If you think you have screwed something up, you can always use the box marked Restore Defaults, and start again.
If you are the type to see how you use the mouse, Logitech has built-in mapping. Either by key presses or by the duration of said key presses, you can enable the software to keep track, and after some use, come back to view the results overlaid on the image of the mouse.
Clicking on the gear symbol gets you to the settings menu. In here, there are more options for various things which were not already shown. Not only that, it is how you obtain firmware upgrades, and is also where you need to be if you want to enable and use Arx Control.
