Why am I experiencing input delay during combat commands in Kai no Kiseki on my Onda B760ITX-B4?

During critical combat turns, my controller felt slightly 'mushy,' with a tiny lag that made precise timing almost impossible. It turns out the USB 3.2 ports on the Onda B760ITX-B4 share southbridge resources with the wireless card, causing constant IRQ conflicts. I tried swapping USB ports, but the latency just kept bouncing between 15-25ms, which made me really paranoid about my hardware. I eventually went into Device Manager, killed every unnecessary USB root hub, and forced the controller port to the highest power state. LatencyMon showed the max latency plummeting from 1200μ s to around 300μ s, and the response became instant. I actually disabled my mouse by mistake during the process, which was a pain until I remapped the USB table. Chipset temps are 42-48℃ and CPU power is between 45-55W. Input monitoring confirms the response is back to normal, with frame times at 5.1-6.4ms.
