Why do I experience ping spikes and rubber-banding during combat in Aka?

During precise parries, my ping would jump from 30ms to 150ms, causing my character to teleport and my attacks to fail. I tried restarting the router and changing channels, but the jitter persisted, making me feel frustrated by my blind reliance on external hardware. I used the GamePP Peripheral Driver Conflict Detector to find a conflict between the NIC driver and a firewall, then optimized the interrupt priority. Ping converged to 28-35ms via Ping Test, packet loss dropped to 0% per GamePP, and NIC temp hit 50-56℃ per HWMonitor.
