Advanced Optimization & Settings
Now let's squeeze every drop of performance from your G203:
On-Board Memory:
Save your settings directly to the mouse so they work on any computer:
- In G HUB, click the "Settings" gear icon
- Enable "On-Board Memory Mode"
- Select which profile to save to the mouse
- Your settings now travel with the mouse - no software needed!
Surface Tuning:
Calibrate the sensor for your specific mouse pad:

- Click "Tune Surface"
- Move the mouse in circles as instructed
- This improves tracking accuracy by 10-15%!
Polling Rate:
The G203 uses 1000 Hz (1ms) polling rate by default - this is perfect! No need to change.
Report Rate:
- 1000 Hz = 1ms response (recommended for all gaming)
- Lower rates (500 Hz, 250 Hz) only useful for troubleshooting USB issues
Game-Specific Profiles:
Create custom profiles that auto-activate when you launch games:
- Click "Profiles" in G HUB
- Create new profile (name it after your game)
- Configure DPI, RGB, and buttons for that game
- Link the profile to the game's .exe file
- G HUB will auto-switch when you launch the game!
Ultimate Performance Setup
For absolute best performance:
1. Use direct USB port (not hub)
2. Disable Windows "Enhance pointer precision"
3. Set DPI to match your game's sensitivity
4. Turn off RGB during tournaments (placebo, but pros do it)
5. Surface tune for your exact mouse pad
Optimize Windows Mouse Settings
G HUB is just half the equation. Windows settings matter too:
Disable Pointer Precision (Enhanced Pointer Precision):
- Open Windows Settings > Devices > Mouse
- Click "Additional mouse options"
- Go to "Pointer Options" tab
- UNCHECK "Enhance pointer precision"
- Set pointer speed to middle (6/11)
- Click Apply and OK
Why This Matters
"Enhance pointer precision" is Windows' mouse acceleration. It makes your aim inconsistent - you MUST disable it for gaming!
Adjust Scroll Speed:
- In the same window, go to "Wheel" tab
- Set to 3-5 lines per notch (personal preference)
- Test in your browser or game
