How to reduce input latency on Jginyue B760M Gaming D4 for Phantom Blade Zero?
That feeling where you press a button and the character reacts half a second later is absolutely lethal in an action game. The USB controller on the Jginyue B760M Gaming D4 had polling intervals swinging between 8-15ms, creating a noticeable delay. I tried swapping between USB 2.0 and 3.0 ports, but the lag followed me everywhere—I actually started thinking my keyboard was dying. I finally forced XHCI mode on in the BIOS and disabled 'USB selective suspend' in the Device Manager. My input lag tester showed response times drop from 18-25ms to a crisp 4-7ms, and the combos suddenly felt fluid. I did have a brief issue where my wireless mouse kept disconnecting after the XHCI tweak, but a driver update sorted it out. The board core is at 45-52℃ and the IO area is 58-63℃. The system panel confirms the response mode is optimized, though the RAM is running a bit warm at 58-63℃.
