Why is my mouse response lagging during sword duels in Kingdom Come II?

During intense sword duels, I felt a strange stickiness in my mouse pointer; this tiny delay is fatal when you need a perfect parry. I tried disabling Windows mouse acceleration, but it had zero effect on the actual latency. I used the GamePP Peripheral Driver Conflict Detector to disable redundant background sync services and installed clean drivers. Response time stabilized at 8-12ms per LatencyMon, and motherboard temps stayed at 45-52℃ per HWInfo64.
