Adjustable Mouse Sensitivity
The adapter allows for adjustment of mouse sensitivity, which is crucial for FPS games. This feature simulates right joystick movement, providing faster and more accurate targeting compared to standard controller sticks. Look sensitivity and aim-down-sight speed can be fine-tuned within the game's settings or potentially through adapter-specific functions (refer to the product's quick start guide for any specific button combinations for sensitivity adjustment).
