How to reduce mouse response latency in Battlefield 2042?

While precision sniping, I felt a strange stickiness in my mouse pointer—a tiny delay that is absolutely lethal on the battlefield. I first tried disabling mouse acceleration in Windows, but it had zero impact on the actual latency, making me very cautious. I then used the GamePP Peripheral Driver Conflict Detector to set redundant background sync services to Manual and reinstalled clean drivers. LatencyMon confirmed response times dropped from 12-35ms to 7-11ms, and HWiNFO64 showed motherboard temps at 45-52℃ with CPU usage at 40-48%.
