Optimizing input response speed on Onda B760ITX-B4 for Neverness to Everness?
That feeling where you press a button and the character reacts half a second later is a total death sentence in an action game, but getting it fixed was an absolute rush. The USB controller on the Onda B760ITX-B4 had polling intervals swinging between 10-18ms by default, causing a visible delay in command transmission. I tried swapping between USB 2.0 and 3.0 ports, but the lag followed me everywhere, making me think my keyboard was the problem. I finally dove into the BIOS, forced XHCI mode to 'Enabled', and disabled 'USB selective suspend' in the Device Manager. Using an input lag tester, the response time dropped from 20-28ms to a crisp 5-8ms, and the gameplay suddenly felt incredibly fluid. I did hit a snag where my wireless mouse started dropping connection after enabling XHCI, but a quick driver update sorted that out. The board core is at 42-48℃ and the I/O area is around 55-60℃. The system performance panel confirms the input mode is fully optimized, with frame generation times now locked at 5.1-6.4ms.
