- Record your desired keystroke actions.
- Save and assign the macro to a button.

Using DPI Settings for Custom Sensitivity
The DPI (Dots Per Inch) button on the G305 can be mapped for more than just changing sensitivity.
Set DPI Levels:
- Click DPI Settings in G HUB.
- Customize up to 5 DPI levels.
- Map the DPI button to cycle through DPI levels or switch between two for sniping and general use.
Creating Game-Specific Profiles
G HUB can detect the active game or software and switch profiles automatically.
To Set This Up:
- Click on the profile name.
- Set the executable or application it should apply to (e.g., valorant.exe).
- Enable automatic switching.
This makes it easy to jump from work to play with different button mappings.
Saving Settings Onboard
The G305 supports onboard memory, meaning you can store one profile directly on the mouse.
- In G HUB, go to the Onboard Memory Manager.
- Select your profile.
- Click Save to Device.
This allows you to carry your configuration even if you’re on a different computer without G HUB.
Advanced Tips
1. Layered Macros
Combine key presses, delays, and mouse actions into one macro for complex commands.
2. Shift Functionality
Assign a “shift” function to one button, allowing other buttons to serve double duty.
3. Game-Specific Downloads
Many games have pre-built profiles available in the G HUB community. Download and tweak to your needs.
