How to fix USB input delay on Maxsun MS-eSport B850ITX?
Man, it feels incredible now! When my blade perfectly parries an attack on screen, the fluidity is just exhilarating. During my initial tests, the USB 3.2 ports on my Maxsun MS-eSport B850ITX WIFI ICE were clashing with the wireless card's IRQ, causing keyboard latency to spike between 15-40ms. I tried switching to a USB 2.0 port, but that capped my mouse polling rate at 125Hz, which was a huge step backward. I eventually went into Device Manager, disabled power management for the wireless card, and used a utility to set the USB controller's interrupt priority to High. My latency tester now shows a rock-solid 4-8ms response time. Every strike is pinpoint accurate. I did get some weird audio popping when I first changed the priority, but dropping the audio sample rate from 192kHz to 48kHz fixed it. Now the board stays at 48-55℃, the wifi module is 52-58℃, and RAM is holding steady at 48-54℃.
