How to resolve mouse response latency and aiming drift in Red Dead 2?

During Dead Eye shooting, I felt a strange stickiness in the mouse pointer; this tiny delay is lethal in a shootout. I first tried disabling mouse acceleration in Windows, but it had zero effect on the latency, making me very cautious. I then used the GamePP Peripheral Driver Conflict Detector to set redundant background sync services to manual and installed clean drivers. Latency stabilized at 8-12 ms per LatencyMon, CPU usage stayed at 45-52% per Task Manager, and temps held at 48-55℃ per HWiNFO.
