  • Keep polling rate reasonable; 500–1000 Hz is fine. Some older games behave poorly above 500 Hz; if you see stuttering, try lowering to 500 Hz.
  • Use a direct USB connection (avoid unpowered hubs or Bluetooth for gaming mouse).
  • In gaming mouse driver utilities (Logitech G Hub, Razer Synapse, etc.), disable any software acceleration/smoothing and set a consistent DPI/CPI.
