Fixing USB interface latency on Jinyue B760M Gaming D5?
My attack commands were lagging by about 120ms on screen, and that 'mushy' feeling is a complete disaster in fast-paced duels. Digging deeper, I found that some USB ports on the Jinyue B760M Gaming D5 were fighting for resources with the motherboard's Interrupt Requests (IRQ), causing latency spikes between 25-60ms. I tried swapping out my peripherals for different brands, but the lag just wouldn't go away, making me realize this was a low-level motherboard issue. I went into the BIOS, forced the USB mode to Gen2, and disabled 'USB selective suspend' in Device Manager. Using a latency tester, the response time plummeted from 42ms to 10-15ms. I did have a brief moment where my mouse disconnected right after the change, but a chipset driver update sorted it out. Southbridge temps are sitting at 52-58℃ and RAM is at 58-63℃. After three intense matches, the controls finally feel instant again.
